About the British Columbia management plan series

This series presents the management plans that are prepared as advice to the Province of British Columbia. Management plans are prepared in accordance with the priorities and management actions assigned under the British Columbia Conservation Framework. The Province prepares management plans for species’ that may be at risk of becoming endangered or threatened due to sensitivity to human activities or natural events.

What is a management plan?

A management plan identifies a set of coordinated conservation activities and land use measures needed to ensure, at a minimum, that the target species does not become threatened or endangered. A management plan summarizes the best available science-based information on biology and threats to inform the development of a management framework. Management plans set goals and objectives, and recommend approaches appropriate for species or ecosystem conservation.

What's next?

Direction set in the management plan provides valuable information on threats and direction on conservation measures that may be used by individuals, communities, land users, conservationists, academics, and governments interested in species and ecosystem conservation.

Executive Summary

Oldgrowth specklebelly (Pseudocyphellaria rainierensis) is a leafy lichen, typically found growing on amabilis fir trees, in close association with yellow cedar, in old-growth rainforests of western North America.

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) designated oldgrowth specklebelly as Special Concern due to the loss of old-growth forests. As well, the species has low dispersal ability and is restricted to nutrient hotspots such as dripzones under old yellow-cedars, toe slope positions, and sheltered seaside forests. It is listed as Special Concern in Canada on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, oldgrowth specklebelly is ranked S2S3 (imperiled to vulnerable) by the B.C. Conservation Data Centre and is on the provincial Blue list. The B.C. Conservation Framework ranks oldgrowth specklebelly as a priority 2 under goals 1 and 3 (1 = contribute to global efforts for species and ecosystem conservation; 3 = maintain the diversity of native species and ecosystems).

The greatest current threat is from logging and wood harvesting.

The management goal is to maintain all known extant populations and any future populations of oldgrowth specklebelly that may be found in British Columbia.

The following management objectives will guide work in the near term:

  1. to secure long-term protection Content Footnote 1for the known populations and habitats of oldgrowth specklebelly;
  2. to determine the levels of real and potential threats to this species and its habitat and to mitigate their effects; and
  3. to confirm the distribution of oldgrowth specklebelly (including new locations) and to reliably determine population trends through monitoring.

assessment Summary - April 2010

Date of Assessment:
April 2010
Common Name (population):
Oldgrowth Specklebelly Lichen
Scientific Name:
Pseudocyphellaria rainierensis
COSEWIC Status:
Special Concern
Reason for Designation:
This foliose, tree-inhabiting lichen is endemic to old-growth rainforests of western North America. In Canada, it is limited to coastal or near-coastal areas of southern British Columbia. Recent discoveries of additional records have only slightly expanded the known range of occurrence, and the lichen remains threatened by ongoing loss of old growth forests through clear-cut logging. The low dispersal ability of its heavy propagules contributes to its rarity, as does its restriction to nutrient hotspots, such as dripzones under old yellow-cedars, toe slope positions, and sheltered seaside forests. It tends to occur discontinuously and on very few trees in the stands where it is established.
Canadian Occurrence:
British Columbia
Status History:
Designated Special Concern in April 1996. Status re-examined and confirmed April 2010.

3. Species Information

3.1 Species Description

Oldgrowth specklebelly is a large, blue-gray foliose (leafy) lichen 5–12 cm across with lobes 1.5–3 cm wide. The vegetative body of the lichen including the lobes comprises the thallus. The upper surface is pale greenish-blue, turning creamy brown in the herbarium. The lobes may be slightly dimpled and the margins have small lobules (small outgrowths) and occasionally coral-like isidia (asexual reproductive structures). The lower surface is dull, white to pale brown, with small hairs and numerous white breathing pores. Oldgrowth specklebelly exists as a symbiotic relationship between a fungi and two algal components, the latter being a cyanobacterium (Nostoc sp.) and a green algae (COSEWIC 2010). The green algae grows in a continuous layer within the lichen whereas the cyanobacteria form localized nodes.

3.2 Population and Distribution

Distribution

Oldgrowth specklebelly is endemic to western North America. It occurs in cool, humid coastal regions from southeast Alaska to northern Oregon. In Alaska it is restricted to within a few km of the ocean, though elsewhere it extends inland to the windward slopes of the Insular Mountains and Cascade Ranges. In British Columbia there are approximately 52 populations occurring within the wet cool subzones of the Coastal Western Hemlock zone (CWH) within the distribution areas of Abies amabilis (amabilis fir) and Xanthocyparis nootkatensis (=Chamaecyparis nootkatensis; yellow-cedar) (Figure 1 and Figure 2) (COSEWIC 2010), which are frequently its host tree and/or closely associated species.

Population Size

There are 56 reported populations of oldgrowth specklebelly within British Columbia. Four of these populations (EO42, EO44, EO46 and Nanaimo Lakes) are considered extirpated, and one population (Hartley Bay (EO6) is considered historical. Therefore, the current total extant number of known populations is 52. Of the 52 current populations, two have been discovered since the 2010 COSEWIC report: Wolf River in Strathcona Park (EO55) on Vancouver Island and near Kitimat at Minette Bay Creek (EO 54). Two previously known populations one east of Kitimat (EO4) and the other at Chilliwack Lake, Provincial Park (EO2) have not been relocated since surveys for the 2010 COSEWIC status report, and their status is unconfirmed.

Most populations of oldgrowth specklebelly consist of 10–30 thalli, with the exception of two populations Caycuse Creek (EO44) and one 0.3 km west of White River (EO31) that have over 500 thalli each on one or two host trees (COSEWIC 2010). Total thalli count for current populations is 2277.

Long description for Figure 1

Figure 1 represents a map of the distribution of Oldgrowth specklebelly, amabilis fir, and yellow-cedar in North America. The Oldgrowth specklebelly is found in the southern end of Alaska within kilometers of the ocean. The map shows 5 locations within this area spread along the coast. In British Columbia, there are 5 locations on Skeena-Queen Charlotte, with 2 locations being in Graham, 1 in Haida Gwaii, and 3 east of Kitimat. A large concentration of locations is represented on the coastal edges of Vancouver Island, with a few being inward on the Insular Mountains. A few locations are also identified in Stafford Valley. In the United States, a large number of locations is identified along the Cascade Range down into Washington and Oregon with a few locations in the middle of the coastal edge of the 2 states. For the amabilis fir, its distribution is represented mostly on the coastal edge of BC and on Vancouver Island, as well as on the Cascade Ranges. The yellow-cedar has a similar distribution as the amabilis fir, in addition to locations identified in Queen Charlotte and in the southern coastal end of Alaska.

Long description for Figure 2

Figure 2 represents a map of the distribution of Oldgrowth specklebelly in British Columbia. The map displays extant, unconfirmed, extirpated, and historical occurrences. Most extant populations are found in the center of Vancouver Island. A few more are found on the north and south end of the island, on Mount St. John, on the east coast of Graham Island and Haida Gwaii, and in Kitimat. One historical population is identified in Hartley Bay. There is one unconfirmed population at the mid southern border of BC and one in Kitimat. Finally, there are 3 extirpated populations in north of Vancouver Island and one in south of Vancouver Island.

3.3 Habitat and Biological Needs of Oldgrowth Specklebelly

Oldgrowth specklebelly occurs in the Coastal Western Hemlock (CWH) BEC zone. It lives on tree branches and trunks of conifers in old-growth forests, particularly in nutrient-rich localities and microsites. Often it occurs in the dripzones of old yellow-cedar trees, at the base of hillsides, and in seaside coves sheltered from strong winds. Other tree species it colonizes are: amabilis fir, subalpine fir (Abies lasiocarpa var. lasiocarpa), Sitka spruce (Picea sitchensis), Douglas-fir (Pseudotsuga menziesii), western red-cedar (Thuja plicata) and western hemlock (Tsuga heterophylla), mountain hemlock (Tsuga mertensiana) and western yew (Taxus brevifolia) (COSEWIC 2010). Oldgrowth specklebelly requires open, humid, forest ecosystems; however, both full sunlight exposure and deep shade are harmful to the species.

Oldgrowth specklebelly is nutrient-demanding and establishes exclusively on the bark of conifers with a pH greater than about 5.0. The primary host tree over most of its range is amabilis fir. Yellow-cedar (Xanthocyparis nootkatensis = Chameacyparis nootkatensis) enhances the nutrient status of trees growing within its dripzone and thus promotes the establishment of oldgrowth specklebelly in habitats where it would otherwise be unlikely to occur (COSEWIC 2010). Yellow-cedar itself rarely acts as a host tree.

Oldgrowth specklebelly exists as a symbiotic relationship between a fungus and two algal components (green algae and cyanobacteria). The fungal component protects the algal component by enveloping it with tissue layers, and provides a steady supply of moisture by conducting water within its cell walls. In turn, the algal or cyanobacteria, through the process of photosynthesis produces sugar and carbohydrates that are used by itself and the fungal partner as an energy source (Brodo et al., 2001).

3.4 Ecological Role

Oldgrowth specklebelly may contribute marginally to the nitrogen cycle due to the nitrogen-fixing blue-green algae found on the lobules (COSEWIC 2010).

3.5 Limiting Factors

Oldgrowth specklebelly occurs in Canada only in coastal temperate rainforests with trees greater than 200–300 years old and therefore is dependent on old-growth forests (COSEWIC 2010).

Another limitation for oldgrowth specklebelly is its growth form; lichens represent a symbiotic relationship between fungus and algal or cyanobacterial components. It is likely to establish only on trees with a bark pH of greater than 5.0 to facilitate production of nitrogen in an accessible form (COSEWIC 2010). Nutrient enrichment is a rather localized phenomenon within the winter-wet rainforests colonized by Oldgrowth Specklebelly, owing to the tendency of heavy rains to remove nutrients from the system. Only in a small number of nutrient-retentive hotspots do nutrients routinely accumulate to levels likely to promote the establishment of tree-dwelling cyanolichens. Such hotspots tend to arise in one or both of two ways, that is, either from the interception of marine aerosols, or from the uptake of nutrients from nutrient-rich soil or bedrock. Both mechanisms operate according to the dripzone phenomenon (Goward and Arsenault 2000).

Dispersal of lobules and isidia (outgrowth of thallus containing algal components) is only within short distances, which may be a limiting factor for distribution (COSEWIC 2010; Sillett and Goward, 1998). Reproduction occurs exclusively through the formation and dispersal of lobules or sometimes isidia. These asexual structures must land on and then affix to a branch segment or trunk that is in a location which provides the optimal combination of light, exposure to wetting, ecological stability and (in the case of conifers) nutrient enrichment. The first three requirements are easily met in most oldgrowth forests, but the fourth – nutrient enrichment – is limiting for this species and must further account for its highly discontinuous distribution. Possibly the relative rarity of oldgrowth specklebelly in the northern portions of its range – including Haida Gwaii –is related at least in part to the absence here of its primary host tree, amabilis fir, as well as to the comparatively recent arrival of its primary facilitator, yellow-cedar (COSEWIC 2010).

4. Threats

Threats are defined as the proximate activities or processes that have caused, are causing, or may cause in the future the destruction, degradation, and/or impairment of the entity being assessed (population, species, community, or ecosystem) in the area of interest (global, national, or subnational) (Salafsky et al. 2008). For purposes of threat assessment, only present and future threats are considered. Content Footnote 2 Threats do not include limiting factors, which are presented in Section 3.5. Content Footnote 3

4.1 Threat Assessment

The threat classification below is based on the IUCN-CMP (World Conservation Union–Conservation Measures Partnership) unified threats classification system and is consistent with methods used by the B.C. Conservation Data Centre. For a detailed description of the threat classification system, see the Open Standards website (Open Standards 2014). Threats may be observed, inferred, or projected to occur in the near term. Threats are characterized here in terms of scope, severity, and timing. Threat "impact" is calculated from scope and severity. For information on how the values are assigned, see Master et al. (2012) and table footnotes for details. Threats for the oldgrowth specklebelly were assessed for the entire province (Table 2).

Table Footnote

Footnote 14

Impact – The degree to which a species is observed, inferred, or suspected to be directly or indirectly threatened in the area of interest. The impact of each threat is based on severity and scope rating and considers only present and future threats. Threat impact reflects a reduction of a species population or decline/degradation of the area of an ecosystem. The median rate of population reduction or area decline for each combination of scope and severity corresponds to the following classes of threat impact: Very High (75% declines), High (40%), Medium (15%), and Low (3%). Unknown: used when impact cannot be determined (e.g., if values for either scope or severity are unknown); Not Calculated: impact not calculated as threat is outside the assessment time (e.g., timing is insignificant/negligible (past threat) or low (possible threat in long term); Negligible: when scope or severity is negligible; Not a Threat: when severity is scored as neutral or potential benefit.

Footnote 15

Scope – Proportion of the species that can reasonably be expected to be affected by the threat within 10 years. Usually measured as a proportion of the species' population in the area of interest. (Pervasive = 71–100%; Large = 31–70%; Restricted = 11–30%; Small = 1–10%; Negligible < 1%).

Return to Footnote o referrer

Footnote 16

Severity – Within the scope, the level of damage to the species from the threat that can reasonably be expected to be affected by the threat within a 10-year or 3-generation timeframe. For this species a generation time of 30 years [T. Goward. pers. comm., 2014] was used resulting in severity being scored over a 100-year timeframe. Usually measured as the degree of reduction of the species' population. (Extreme = 71–100%; Serious = 31–70%; Moderate = 11–30%; Slight = 1–10%; Negligible < 1%; Neutral or Potential Benefit > 0%).

4.2 Description of Threats

The overall province-wide Threat Impact for this species is High. Content Footnote 4 This overall threat considers the cumulative impacts of multiple threats. The greatest threat is from logging and wood harvesting (Table 2). Details are discussed below under the Threat Level 1 headings.

IUCN-CMP Threat 3. Energy Production & Mining
3.2 Mining & Quarrying

Aggregate mining may occur at one locality near Kitimat at Europa Creek (EO51) (COSEWIC 2010). As well, if any mining did occur, the area would likely be logged first, host trees for oldgrowth specklebelly would be removed, and fragmentation of habitat increased.

3.3 Renewable Energy

Numerous independent power projects (IPPs) have been applied for across the province, which could potentially affect oldgrowth specklebelly in several ways. One is the removal of waterfall mist, which is known to provide essential habitat for rare lichens through a combination of nutrient enhancement, thermal moderation, and ongoing moisture supply (Bjork et al. 2009). As well, building of the IPPs would involve removal of trees, which could include host trees for oldgrowth specklebelly. Currently one locality at Europa Creek (EO51) has a hydroelectric development (COSEWIC 2010). Because IPPs generally occur in valley bottoms, tree removal associated with road building has a potential to curtail dispersal by this species. The resulting increased fragmentation could decrease the ability of the species to disperse into adjacent forests due to increased edge effect (T. Goward, pers. comm., 2014). As well, the increase in edge effect would raise the light levels and decrease humidity, thereby decreasing the amount of suitable habitat.

IUCN-CMP Threat 4. Transportation & Service Corridors
4.1 Roads & Railroads

Roads that are developed for logging will affect oldgrowth specklebelly, in particular since both the species and mainline logging roads generally occur in valley bottoms. On the north part of Vancouver Island, recent logging roads in this area of high incidence of the species could have removed thousands of individual lichens. Fragmentation of the habitat by logging roads decreases the ability of the species to disperse into adjacent forests, and also decreases the amount of suitable habitat available for the species to colonize (T. Goward, pers. comm., 2014).

4.2 Utility & Service Lines

As every IPP will have a utility corridor associated with it, the establishment of such a corridor could potentially remove habitat of oldgrowth specklebelly and would increase the edge effects as described above when it occurs in that same area.

IUCN-CMP Threat 5. Biological Resource Use
5.3 Logging & Wood Harvesting

Although some proportion of the locations are in old growth management areas (six populations), in wildlife tree retention areas Content Footnote 5 (WTRAs) (six populations), and riparian reserve zones (six populations), these areas have no legislated protection Content Footnote 6 at this time under the Forest and Range Practices Act. As such, of the 52 extant populations, all but 4–5 are on public lands and subject to logging. Most populations are localities on northern Vancouver Island under an active tree farm license. Logging and wood harvesting will remove host trees as well as habitat-creating trees (e.g., yellow cedar) and therefore reduce suitable habitat for oldgrowth specklebelly. These populations should be monitored from time to time to assess rates of decline from future logging operations (T. Goward, pers. comm., 2014).

IUCN-CMP Threat 10. Geological Events
10.2 Earthquakes/tsunamis

Low elevation populations along the coast are vulnerable to habitat loss or salt water immersion if a tsunami occurs (e.g., related to predicted strong seismic activity off southern Vancouver Island (Province of B.C. n.d.). The Haida Gwaii populations on Graham Island (Tow Hill area - EO5 and Kumdis Bay - EO52) would likely be extirpated by such an event.

10.3 Avalanches/landslides

On mainland localities landslides could be caused by torrential rain events as well as by slope destabilization in connection with logging road construction. The coastal locations are already exposed to drenching winter storms and with climate change these events are expected to increase in frequency and severity (Gayton 2008). Avalanches or landslides would remove the habitat for the host trees and therefore would be no habitat for oldgrowth specklebelly growth and reproduction.

IUCN-CMP Threat 11. Climate Change & Severe Weather
11.4 Storms & Flooding

Loss of host trees during storms and flooding has a potential to negatively impact oldgrowth specklebelly. As well, field observations suggest that oldgrowth specklebelly is sensitive to continuous exposure to rainwater during prolonged winter storms. Increasing severity of winter storms along the coast has a potential to result in its loss from some locations (T. Goward, pers. comm., 2014).

5. Management Goal and Objectives

5.1 Management Goal

To maintain all known extant populations and any future populations of oldgrowth specklebelly that may be found in British Columbia.

5.2 Rationale for the Management Goal

The overall goal is to maintain all known extant populations of the species within British Columbia. This includes the current extant populations as well as any populations that are found in the future. No quantitative management goal is possible for oldgrowth specklebelly as basic population demographics and trends are unknown for all populations. As with many other rare plant species, we lack adequate information about the historical distribution of oldgrowth specklebelly, however, it was likely never more widespread. Given this species' dependence on fragmentation for dispersal (i.e., it's a very slow disperser), and given that it grows more or less exclusively in oldgrowth forests not prone to large-scale disturbance, it has likely been expanding its range gradually over the past 10,000 years since deglaciation( T. Goward, pers. comm. 2015).

This lichen is endemic to western North America. All 56 reported populations in Canada occur in British Columbia in a limited area along coastal areas of the southern portion of the province. Habitat loss is likely to result from logging and wood harvesting, and the low dispersal ability of this lichen contributes to its rarity. As well, habitats containing nutrient hotspots, such as dripzones that occur under old yellow cedar in sheltered seaside forests are limited (COSEWIC 2010).

Conservation of this species should focus on improving the probability that it will persist in the wild. However, to prevent oldgrowth specklebelly from becoming threatened or endangered, all known extant populations should be maintained. Once the knowledge gaps have been fulfilled, the goal can be refined.

5.3 Management Objectives

The following management objectives will guide work in the near term:

  1. to secure long-term protection Content Footnote 1 for the known populations and habitats of oldgrowth specklebelly;
  2. to determine the levels of real and potential threats to this species and its habitat and to mitigate their effects; and
  3. to confirm the distribution of oldgrowth specklebelly (including any new populations) and to reliably determine population trends through monitoring.
