“…Grazing and other damage was a problem in our trial and has been reported elsewhere Gustafsson et al 2013), it may be necessary to physically remove invertebrates from the adjacent bark. For future trials, we recommend applying a large number of gel-filled gauze packets multiple times to mimic natural dispersal, and to accommodate failures due to high rainfall events, droughts and predation.…”

“…This may suggest that different factors favour propagule immobilization and early development than those that favour lobe formation (Scheidegger 1995;Scheidegger et al 1995;Hilmo et al 2011;Gustafsson et al 2013). Successful lobe formation was low, occurring in only 13% of packets and was actually slightly more successful on the south sides of trees (seven of thirteen packets), despite survival and vitality of soredia being higher on the north sides of the trees rather than the south.…”

“…Ott (1987) found that seasons have an influence on the microclimate of site locations, and the speed of development of propagules is dependent on the season of dispersal. Transplanted lichens over time can be affected by changes to microclimate due to forest succession, competition with other organisms such as bryophytes, and herbivory by mites, gastropods and other invertebrates Gustafsson et al 2013). Translocation of soredia during optimal seasonal conditions could reduce the crucial time period needed for fixation and establishment.…”

“…It may be appropriate to trial multiple applications of lichen propagules at a site to increase translocation success. Transplanted lichens over time can be affected by changes to microclimate due to forest succession, competition with other organisms such as bryophytes, and herbivory by mites, gastropods and other invertebrates Gustafsson et al 2013). Our study sites are at the edge of restoration plantings, and one of the two was unexpectedly shaded by invasive tree species as the experiment progressed.…”

Summary Lichens are an essential component of ecosystem processes. Many lichen species are habitat specialists that rely on specific tree substrates and moisture regimes of old‐growth forests and are not found in early‐successional forests, small isolated forest fragments or restoration projects, making them useful bioindicators of forest health. Pressures from habitat loss and fragmentation have affected the viability and survival of lichen species that are often limited by low dispersal ability. As a rule, lichens are rarely included in ecological restoration programmes despite translocation methods being available. We trialled a combination of two of the more successful methods (gauze packets and use of adhesive gels). Three different gelling agents were used in attempt to immobilize living soredia of the lichen Crocodia aurata on trunks of Ti Kouka/Cabbage Tree (Cordyline australis) for long enough for them to develop into thallus lobes. The effectiveness of these methods was tracked over a 2‐year period. Our results show that all three gel treatments were effective at immobilizing soredia in the gauze packets. Lobe formation occurred in all three gel treatments after 36 weeks, with methyl cellulose the most successful with six packets producing lobes, five Ac‐Di‐Sol® and two agarose packets also producing lobes, out of a possible total 100 gauze packets. Lobe formation was slightly more successful on the south sides of trees (seven of thirteen packets), despite initial survival and vitality of soredia being higher on the north sides of the trees.

Silvicultural strategies for lichen conservation: Smaller gaps and shorter distances to edges promote recolonization

Conservation of epiphytic lichens in managed forest landscapes relies on understanding limitations to their dispersal and establishment after harvesting. A hot spot for cephalo-and cyanolichens, the Kispiox inland temperate rainforest of British Columbia, Canada, is an example of where forest managers seek silviculture options that allow for forest harvesting to continue, while also conserving threatened species. To characterize colonization of these lichens (including the nationally threatened Nephroma occultum and Lobaria retigera), we quantified thalli on 25-year-old regenerating spruce trees at varying distances from forest edges in logged openings of different sizes surrounded by mature (160 years) or old-growth (≥350 years) forest. Lichen colonization 25 years after logging was influenced by distance from the forest edge, surrounding forest age, and opening size. Total mean colonization and number of species per three branches were 81 thalli and 8 species at the forest edge, declining to 18 and 4, respectively, approximately 50 m into the openings. Colonization of most species reached minimum levels within 80 m. Nationally threatened species and old-forest associates had higher abundances and longer colonization distances in openings surrounded by old-growth forests; whereas widespread species had greater colonization when surrounded by mature forests. Logged gaps <0.6 ha promoted higher and more diverse lichen colonization than clearcuts (>3.8 ha). This study demonstrates that forest managers should consider the spatial patterning of harvesting, with smaller openings and shorter distances between edges (likely in tandem with higher levels of retention) in forests rich in epiphytic lichens to facilitate their recolonization and conservation.
