“…For example, variation in livestock grazing, agriculture, and prairie dog control between ownership strata could influence WTPD habitat and population dynamics (Pauli and Buskirk 2007, WGFD 2017). Unfortunately, data on private lands in Wyoming and worldwide are generally lacking (Haufler and Kernohan 2009, Pocewicz et al 2009), so we were unable to test these effects. Quantifying these land‐use factors in future research could improve our understanding of WTPD population dynamics and better inform conservations efforts.…”

“…Research conducted to assess population parameters and inform management decisions is necessarily restricted to a study area; however, the delineation of the area itself can strongly influence research conclusions (Wiens 1989, Knight 1999, Spies et al 2007). Wildlife research is often limited to public land due to challenges accessing private land (Haufler and Kernohan 2009), but critical drivers of population patterns, such as habitat quality, ecosystem management, or land‐use, often vary with land ownership (Scott et al 2001, Spies et al 2007, Donnelly et al 2016). Studies restricted to a single ownership may therefore yield incomplete and potentially misleading results if a substantial portion of the population or habitat is omitted, which in turn may influence management actions.…”

“…Studies restricted to a single ownership may therefore yield incomplete and potentially misleading results if a substantial portion of the population or habitat is omitted, which in turn may influence management actions. Research that includes multiple land ownerships can thus more effectively inform conservation and management and, potentially, result in new ecological insights (Knight 1999, Haufler and Kernohan 2009, Kremen and Merenlender 2018).…”

Crossing boundaries in conservation: land ownership and habitat influence the occupancy of an at‐risk small mammal

Ecological research is critical for informing management of at-risk species, for example, by identifying what drives occupancy of species across landscapes. However, restricting research to public land and omitting private land, as commonly occurs in ecological research, can bias inferences because important drivers of population and community patterns may vary with land ownership. We conducted a landscape-scale study of a species of conservation concern, white-tailed prairie dog (WTPD; Cynomys leucurus), across multiple land ownerships in Wyoming. We quantified how WTPD occupancy varied with both land ownership and biotic and abiotic factors. We established a baseline occupancy rate for WTPD in Wyoming, and quantified how this baseline would have been biased if we had restricted our study to public land. We surveyed 440 sites throughout the Wyoming range of WTPD, which included sites on public (275), private (80), checkerboard (55), and Wind River Indian Reservation (30) land. We found that WTPD occupancy varied significantly with land ownership and elevation, with WTPD being four times as likely to occupy private as public land at the median study area elevation. This difference in occupancy may have been driven by variation in habitat quality between ownership types, but we could not definitively determine the underlying cause. Regardless of land ownership, WTPD occupancy increased with bare ground, but also when recent plant biomass (as estimated by NDVI) was higher than a site's long-term average biomass. In other words, WTPD tended to occupy sparsely vegetated sites, but occupancy increased with short-term increases in biomass. The strong land ownership effect illustrates how study area delineation in relation to land ownership can influence research inferences and management actions, and why it is counterproductive to presuppose that certain land ownerships contain low-quality habitat. Ecologically, the variation in occupancy resulting from long-term site conditions, such as overall density of vegetation, relative to short-term site conditions, such as changes in plant biomass, can be used to improve long-term population monitoring for WTPD.

“…As it is considered that there are not enough public areas under protection in terms of their number and distribution (GOTTFRIED et al, 1996), conservation in private areas, in fragments of forest and other types of vegetation is fundamental in protecting nature and is an important component of the national strategy for sustainable use of natural resources (ELI, 2003;HAUFLER;KERNOHAN, 2009;METZGER, 2002). In Brazil, roughly 70% of the remaining natural vegetation is located on private land (SPAROVEK et al, 2012), to which Law No 12.651/2012 applies.…”

De acordo com a legislação ambiental brasileira, os Sistemas Agroflorestais (SAF) constituem uma alternativa para recomposição e uso das Reservas Legais (RL). Todavia, uma vez que SAF compreendem práticas muito heterogêneas, é pertinente discutir se, e quais Sistemas são adequados para cumprir as funções dessas áreas protegidas. O presente artigo visa apresentar elementos e considerações pertinentes a essas questões, com base em ampla revisão bibliográfica. A bibliografia aponta que o valor e potencial dos SAF para a conservação são limitados e controversos; a sustentabilidade e os benefícios proporcionados por esses Sistemas dependem de sua tipologia (estrutura e diversidade), da paisagem do entorno e da condução do manejo. Portanto, é imprescindível estabelecer critérios e limites para o uso dos SAF na restauração e exploração das RL, que considerem o grau de conservação e a extensão das RL e baseiem-se em estudos sobre a viabilidade ecológica e/ou ambiental desses Sistemas a longo prazo.

“…Atualmente, cerca de 70% da vegetação natural remanescentes está distribuída em terras privadas (SPAROVEK et al, 2012), sendo essas as que mais contribuem para a questão da conservação, uma vez que a quantidade de áreas públicas voltadas para a proteção, em um nível nacional, é considerada insuficiente tanto em quantidade como em distribuição (GOTTFRIED et al, 1996). Assim, a conservação e recuperação de áreas localizadas em terras privadas torna-se um ponto essencial para a conservação da natureza (ELI, 2003;HAUFLER & KERNOHAN, 2009;METZGER, 2002…”

Multicriteria evaluation in the implementation of legal reserves Legal Reserve (LR) is a form of protected natural area, which consider different criteria, defined by the law for its establishment. The LR implementation has common objectives with landscape restoration, which involve different areas of knowledge. The main issue, however, is related with the best location of LR, which summarizes the main needs of society (economic, ecological and social) as well, and of ecosystems. The Multicriteria Evaluation (MCE), that is one of the decision-making techniques, permits the integration of criteria for decision-making and, so, can support the LR allocation. Thus, the main objective of this study was the identification of areas suitable for forest restoration, aiming at the definition of area for LR implantation, through one MCE method, named Ordered Weighted Average (OWA). The following criteria set were selected, consulting the experts in areas related with the study: proximity to surface water, proximity to forest patches, slope, neighbors to forest patches and distance to roads. The experts also helped to define the "factor weight" (set of weights that express the relative importance of the criteria). As the next step, we evaluated the influence of criteria in decision-making that supported the criteria ranking. For apply OWA method, we pre-defined the tradeoffs levels (T): low (T=0.3618), medium (T= 0.5570) and high (0.7879). The order weights supported this process. They control the level of tradeoff between weights of factor, considering the importance and influence of factor in the decision-making process. We obtained, as result, six scenarios (OWA1 to OWA6), indicating suitable areas for forest restoration, aiming at the definition of area for LR implementation. OWA1 and OWA3 have high correlation between areas suitable. For the other side, OWA4 and OWA5 present low correlation, as consequence of its values of T and risk (R) values, for decision-making. The scenario OWA3, with medium-low risk for decision-making (T=0.5570 and R=0.2503), proposed the best identification of areas suitable for forest restoration, aiming at the definition of area for LR implantation. The sensibility analysis of OWA3 indicated that the select criteria were important for its production, as the influence of criteria (controlled by order weights). According OWA3, the implementation of LR should begin by areas susceptible to erosion, which supports the connectivity among forest patches, as pre-defined by the law. We concluded that OWA method permits the definition of priority areas for LR implantation, considering the landscape restoration and; the sensitivity analysis, supported by statistical analysis of correlation, is a suitable methodology for evaluation of criteria, in terms of its influence on the decision-making process.
