“…A species with a single population is vulnerable to extinction simply due to being subject to factors that vary stochastically, which is why the introduction of species in new locations greatly increases their chances of survival (Maunder, 1992). In this sense, the actions taken in the present study have helped restore the original population of A. bermejoi and reduced its probability of extinction by increasing the number of populations of this plant in the wild, and so providing additional sources for seed collection for use in ex situ techniques, without disturbing the natural regeneration capacity of the original population.…”

“…Population restoration techniques have become widely used tools for the conservation of threatened plant species in recent decades (Maunder, 1992;Hodder & Bullock, 1997;Escudero & Iriondo, 2003;Heywood & Iriondo, 2003;. The IUCN (1998) states that a "reintroduction" is an attempt to establish a species in an area that was part of its range in the past, while a "benign introduction" (hereafter, introduction) is the attempt to establish a species, for purposes of conservation, outside of its range, but in an appropriate habitat and eco-geographical area.…”

“…Thus, recruitment is considered the most reliable parameter indicating a successful reintroduction because it reflects many components of the life cycle (Pavlik, 1996;Sutter, 1996). However, the ultimate success of a reintroduction project, i.e., autonomous maintenance of populations, can be determined only after many years of follow-up (from 10 years to several decades) (Maunder, 1992;Pavlik, 1996;Milton & al., 1999), depending on the generation time for the species. A benign introduction is an action that is merits in situ actions when it makes a significant contribution to the conservation of a species and when there is no possibility of reintroducing the species to sites it inhabited historically (IUCN, 1998).…”

“…A benign introduction is an action that is merits in situ actions when it makes a significant contribution to the conservation of a species and when there is no possibility of reintroducing the species to sites it inhabited historically (IUCN, 1998). Species that are found at a unique locality in the wild fall into this category (Maunder, 1992). In these cases, even when imminent threats are unknown it is advisable to diversify the risk by increasing the single population to a minimum of three subpopulations (Martinell & al., 2011).…”

“…In addition, many negative experiences remain unpublished, such that a review of the scientific literature does not allow an accurate assessment of the actual success that these techniques have achieved . Paradoxically, not taking action in critical cases can represent an equal or greater risk (the extinction of a species in the worst case scenario) compared to an attempt to restore the original population (Maunder, 1992), so that managers are often taking a risk whatever decision is reached.…”

Morphological and ecological responses to a conservation translocation of powan (Coregonus lavaretus) in Scotland

ABSTRACT1. The establishment of refuge populations has become a common management tool for threatened fish species in recent years, yet the effects of translocation are not fully understood in a conservation context.2. This paper examines the hypothesis that phenotypic changes have occurred during the formation of two refuge populations of the nationally rare powan (a freshwater fish species) which were established in Loch Sloy and Carron Valley Reservoir in Scotland.3. Significant differences in head morphology, size and growth between the founder and refuge populations and between the two refuge populations were demonstrated. These changes are probably due to a combination of founder effects, intense selection and phenotypic plasticity. These changes can undermine the rationale behind the establishment of refuge populations.4. The results call into question the usefulness of translocation as a conservation measure; however, there are times when this is the only viable management option available. The future of translocation and the validity of establishing refuge populations for powan conservation are discussed.

ABSTRACT1. The choice of suitable sites for establishment of a new population of a species is the first step in a translocation programme. However, evaluation of a large number of sites can be demanding of time and money; practitioners need time-and costeffective evaluation tools.2. A predictive model for the preliminary evaluation of potential reintroduction sites was developed using the endangered quillwort Isoëtes malinverniana as a case study. The reliability of three water habitat variables (pH, conductivity, and clarity) as predictors of the presence/absence of I. malinverniana was tested. Three sets of logistic models were produced on the basis of the mean values of pH and conductivity measured over 3, 4 and 6 months to understand whether frequency of measurement affected the reliability of the models. Models of each set were ranked according to AIC and their reliability was then tested using data from the literature.3. The conductivity of water and pH were the most effective predictors of the suitability of sites for the reintroduction of I. malinverniana. In particular there was a negative relationship between the presence of I. malinverniana and these variables.4. Because of seasonal fluctuations in the variables considered, at least 4 months monitoring are required to obtain reliable results. Despite this, the method is still advantageous in terms of costs, compared with repeated measurements of a wide range of chemical characteristics at a large number of sites.5. The main goal of this method is to limit expensive chemical analysis to a few sites chosen after the exclusion of unsuitable sites, through application of the model.Considering the similar ecophysiological features of quillworts from oligotrophic waters, the same model or conceptual framework could be applied to other quillworts and isoetid species growing in degraded areas and needing active conservation.2
