“…Whether the reintroduction of bull trout into the Wallowa River watershed represents a success is not completely clear. The definition of reintroduction success is a subject of considerable debate (see Haskins, 2015; Robert et al, 2015) and criteria are often poorly defined (Godefroid et al, 2011). Given bull trout are no longer absent from in the Wallowa River watershed, are spawning successfully and reproducing naturally, there are certainly components of a successful reintroduction.…”

“…With climate change as an important concern for species conservation (Bellard et al., 2012; Thomas et al, 2004; Thuiller et al., 2005; Urban, 2015), translocations represent an opportunity for practitioners to contribute to the migration of populations towards the poles, or higher up in altitude, to cooler climatic conditions, thus mitigating the deleterious effects of warming (Aitken & Whitlock, 2013; Brooker et al, 2011; Fahselt, 2007). Review articles on plant translocations have focused on an assessment of the success of translocations, and the factors determining that success (Dalrymple et al., 2011; Godefroid et al., 2011; Menges, 2008; Silcock et al., 2019), although the criteria for success are themselves a subject of debate (Haskins, 2015; Robert et al., 2015a, 2015b; Seddon, 2015; Shier, 2015). Curiously, no studies are available that examine the geographical and climatic differences between the natural origins of translocated plant material and its final destination.…”

Plant translocations in Europe and the Mediterranean: Geographical and climatic directions and distances from source to host sites

et al. 2021

Although the number of plant translocations has been rapidly increasing for two decades, no study is available to date that examines the directions and distances of plant displacements, which is essential (though not sufficient) information for considering translocations as a management tool to enable species to cope with the consequences of climate change. In this paper, we study the geographical and climatic directions and distances from source to host sites in 638 source‐and‐host site pairs of plant translocations that aimed to achieve viable populations in the last decades in the Western Palearctic (Europe and the Mediterranean). Translocation distances ranged from 0 to 661 km, but were generally short, most (82%) being <25 km, due to both ecological considerations and legal and administrative constraints. The host sites were not preferentially located in any geographical direction or in any altitude relative to the source sites. In contrast, on a climate compass constructed from a principal component analysis of seven bioclimatic variables, the host sites were slightly, but significantly, under colder climatic conditions than the source sites. This observation appears more to be the consequence of an effort to counteract already felt effects of climate change than to anticipate future changes. The climatic distance between source sites and actual host sites was generally smaller than between source sites and randomly selected host sites at a given distance or within a given geographical area, which may be the result of a desire to minimise climatic differences or differences in other ecological factors correlated with climatic differences. Synthesis. This study is the first to compare, geographically and climatically, the source sites of biological material and the host sites in translocations of wild plant species to obtain viable populations. Past translocations in the Western Palearctic are in line with mitigating the consequences of global warming on plant species because the host sites were in slightly cooler conditions than the source sites. Despite this, climate considerations seem to have little been taken into account in plant translocation projects and will certainly have to be much more so in a future with rapid anthropogenic climate change.

“…This method can estimate the population opportunity to recover based on species-specific data and models (Akçakaya and Sjögren-Gulve 2000). It is often used in conservation priorities that focus on populations (Morrison et al 2016) and also be used to make predictions of a population (Haskins 2015). It helps to assess the extinction risk of endangered species and to identify key factors that affect population status and prospects for sustainability (Zhang and Zheng 2007).…”

Abstract. Ihsan M, Mardiastuti A, Masy’ud B, Mulyani YA. 2021. Population status and sustainability of Yellow-crested cockatoo (Cacatua sulphurea sulphurea) on Pasoso Island, Central Sulawesi, Indonesia. Biodiversitas 22: 3277-3283. Yellow-crested cockatoo (Cacatua sulphurea sulphurea) is a sub-species of Cacatua sulphurea which is spread in Sulawesi and several surrounding islands, including on Pasoso Island. This cockatoo population is under tremendous pressure until categorized as critical. So far, there is no comprehensive information about population status and sustainable population size. The objective of this research area was to assess the current status or size of the population, study the size of the sustainable population and study the determinants factor of the Yellow-crested cockatoo population sustainability on Pasoso Island. The result showed that the population of the Yellow-crested cockatoo in Pasoso Island was only 3 individuals, consists of 2 adults as the parent, and 1 young individual. From 5 analyzed scenarios of the minimum sustainable population size, the 4.1 scenario is the best scenario to maintain the sustainability of the Yellow-crested cockatoo population on Pasoso Island, which is a minimum population size of four pairs (8 adult individuals). The determinants of population sustainbility analysis with the minimum sustainable population size (8 individuals or 4 pairs of broodstock) showed that inbreeding and predation as determinant factors. These factors need to be controlled through mating management and predator control by both humans and carnivorous animals.
