“…Similarly, the same correlation was observed by Trebs et al in 2009. The diversity and abundance of lichens are considered as indicators of environmental quality, where high values correspond to good air quality (Asta et al, 2002a(Asta et al, , 2002b. In addition to the air quality, a combination of bark pH, light, humidity, tree diameter, tree height and distribution is important in determining the richness of lichens (Kotelko et al, 2008). The results of the present study showed that forest islands are highly diverse compared to the continuous forest.…”

Horton Plains National Park (HPNP) has been declared as a world heritage site, because of its unique biodiversity. Die-back of certain areas of this park is widely believed to be due to acidic precursor depositions carried over from other parts of the country and also from neighboring countries. Air pollution data for the two pollutants, NO 2 and SO 2 were obtained from the passive air sampling method. The data revealed that the concentrations of ambient NO 2 and SO 2 were very low in the HPNP. The variations of ambient NO 2 and SO 2 concentrations during the study period showed insignificant positive correlation (p≥ 0.05) with the rainfall data. Considering the variations of these two pollutants with Relative Humidity and the number of vehicles visiting HPNP, both pollutants had insignificant positive correlation. The Index of Atmospheric Purity (IAP) value obtained for the whole area of the HPNP was 54.22. This value belongs to the quality level 5 which represents the 'very low' pollution level. The results including lichen distribution and air quality data could confirm that the ambient air quality at HPNP is very high. The high diversity of lichens and the minimum levels of air pollutants suggested that the forest health of HPNP is at a favorable level. Therefore, it is essential to maintain at least the current air pollution level of HPNP in order to conserve the forest and its biodiversity.

“…Genetic diversity of lichen in the boreal forest is thought to be relatively low due to asexual reproduction being a major strategy for colony expansion (Kotelko et al 2008). As such, the possibility for having a negative impact on the genetics of lichen population structure is probably low.…”

The development of habitat restoration techniques for restoring critical woodland caribou (Rangifer tarandus caribou) winter habitat will play an important role in meeting the management thresholds in woodland caribou recovery plans. The goal is to restore disturbed environments within critical winter habitat for the declining woodland caribou. Woodland caribou are diet specialists, utilizing lichen-rich habitat for forage during winter months. Cladonia sub-genus Cladina is the most frequently eaten species during this time. Herein, we provide: 1) A review of previously used methods for transplanting Cladonia sub-genus Cladina and their feasibility in restoring woodland caribou winter habitat; 2) A stepby-step protocol on how to carry out a terrestrial lichen transplant program (using Cladonia sub-genus Cladina and C. uncialis); and, 3) An evaluation of our protocol through the establishment of a case study in northern British Columbia. Our results indicate that transplanting C. sub-genus Cladina fragments is the most efficient technique for transplanting terrestrial lichen communities, but transplanting lichen 'patches' or 'mats' may also be effective.Key words: Cladonia, Cladina, reindeer lichen, restoration, winter habitat RÉSUMÉLa mise au point de techniques de réhabilitation pour restaurer l'habitat vital d'hiver essentiel du caribou forestier (Rangifer tarandus caribou) jouera un rôle important pour l'atteinte des seuils d'aménagement dans les plans de rétablissement du caribou forestier. Il s'agit en fait de restaurer les environnements perturbés dans les domaines vitaux pour la caribou forestier dont la population est en déclin. Le caribou forestier a une diète spécifique et compter sur les habitats riches en lichen pour s'alimenter durant les mois d'hiver. C' est principalement la Cladonia du sous-genre Cladina dont il se nourrit durant cette période. Dans cet article, nous proposons: 1) Une analyse des méthodes utilisée précédemment pour transplanter la Cladonia du sous-genre Cladina et leur potentiel pour restaurer l'habitat d'hivernement du caribou forestier; 2) Un protocole détaillé pour réaliser un programme terrestre de transplantation (avec la Cladonia du sous-genre Cladina et C. uncialis); et, 3) Une évaluation de notre protocole au moyen d'une étude de cas que nous avons réalisée dans le nord de la Colombie-Britannique. Nos résultats indiquent que la façon la plus efficace pour transplanter des communautés de lichens terrestres consiste à transplanter des fragments de C. sous-genre Cladina, mais qu' on peut aussi la transplanter sous forme de « talles » (patches) ou de « plaques »' (mats).

“…Yet, their distribution within suitable habitat has a decidedly 'weedy' appearance; they appear as matrix species within several decades of disturbance, forming thick carpets and 'cushions' only when mature, and often form a thin but continuous cover in early stages of development (Yarranton 1975). In addition, recent genetic research has demonstrated both high incidence of polymorphism among mats and higher than expected frequencies of apothecia in mature mats, suggesting that sexual, spore-based dispersal may be an important mechanism in some areas (Beard and DePriest 1996, Jahns et al 2004, Robertson and Piercey-Normore 2007, Kotelko et al 2008). …”

“…Dispersal processes are less well known in feathermosses; most species reproduce both vegetatively, through fragmentation and lateral growth, and by spore production, but whether one mode is more dominant under natural conditions, or responds to environmental parameters is uncertain (Frego and Carleton 1995b, 0kland and Bakkestuen 2004, Kotelko et al 2008. Observations that they have similar genetic diversity to vascular plants (Cronberg et al 2006), and that they can rapidly increase in response to changes in environmental conditions (Nelson and Halpern 2005), indicate that they are unlikely to be dispersal limited, despite relatively low sporophyte frequency in some locations (Frego and Carleton 1995a).…”

“…Although many studies show strong support for an influence of the forest canopy on understory development, the relationship has rarely been demonstrated using continuous data. Those researchers who conclude that the canopy drives understory development often cite the mechanisms of moisture and light regulation, which are correlated with the age of the stand (Lechowicz and Adams 1974, Oksanen and Ahti 1982, Kershaw 1977, Hunt et al 2003, Simon 2005, Uotila et al 2005, Kotelko et al 2008); this agrees with the 'relay floristics' (RF) model of succession (Egler 1954). Those who detect little or no canopy influence may conclude that the understory community is primarily structured by the slow expansion of species that are initially present due to stochastic dispersal events or disturbance refugia (Fortin et al 1999, Kembel and Dale 2006, Pharo and Vitt 2000, Frego and Carleton 1995b.…”
