Protected areas not likely to serve as steppingstones for species undergoing climate‐induced range shifts

Global Change Biology, Год журнала: 2023, Номер 29(10), С. 2681 - 2696

Species across the planet are shifting their ranges to track suitable climate conditions in response change. Given that protected areas have higher quality habitat and often harbor levels of biodiversity compared unprotected lands, it is assumed can serve as steppingstones for species undergoing climate-induced range shifts. However, there several factors may impede successful shifts among areas, including distance must be traveled, unfavorable human land uses along potential movement routes, lack analogous climates. Through a species-agnostic lens, we evaluate these global terrestrial area network measures connectivity, which defined ability landscape facilitate or movement. We found over half two-thirds number units globe at risk connectivity failure, casting doubt on whether many successfully undergo areas. Consequently, unlikely large under warming climate. As disappear from without commensurate immigration suited emerging (due failure), left with depauperate suite Our findings highly relevant given recent pledges conserve 30% by 2030 (30 × 30), underscore need innovative management strategies allow shifts, suggest assisted colonization necessary promote adapted

Mature and old-growth forests contribute to large-scale conservation targets in the conterminous United States

Mature and old-growth forests (MOG) of the conterminous United States collectively support exceptional levels biodiversity but have declined substantially from logging development. National-scale proposals to protect 30 50% all lands waters are useful in assessing MOG conservation targets given precarious status these forests. We present first coast spatially explicit assessment based on three structural development measures—canopy height, canopy cover, above-ground living biomass assess relative maturity. were displayed by major forest types ( n = 22), landownerships (federal, state, private, tribal), Gap Analysis Project (GAP) management overlaid NatureServe’s Red-listed Ecosystems species, biomass, drinking water source areas. total ∼67.2 M ha (35.9%) classes scattered across 8 regions with most western regions.

Options for prioritizing sites for biodiversity conservation with implications for “30 by 30”

Biological Conservation, Год журнала: 2021, Номер 264, С. 109378 - 109378

International and national initiatives aim to conserve at least 30% of lands waters by 2030. To safeguard biodiversity, conservation actions must be distributed in places that represent ecosystem species diversity. Various methods prioritizing sites for have been used local global assessments. However, the performance consequences alternative are usually unknown. Such comparisons needed confidently implement international initiatives. Here, we compared four widely-used contiguous United States conserving mammals, birds, amphibians, reptiles. Specifically, calculated mapped richness, rarity-weighted two complementarity-based prioritizations (additive benefit function [ABF] core area zonation [CAZ] software Zonation). We maps derived from these alternatives with respect spatial locations overlap, patch size distributions top-30% priorities, existing ownership protected-area status. species-accumulation curves across ranked priorities evaluate results total area. Mapped sizes highest varied taxonomic class method prioritization. Complementarity-based (ABF CAZ) more efficiently represented than based on richness or especially taxa higher beta diversity (amphibians). ABF CAZ also resulted greater opportunity top richness. Area-based targets, such as "30 30" initiative, distribute limited resources ways all species. Our show configuration, performance, vary among prioritization classes.

Identifying key federal, state, and private lands strategies for achieving 30 × 30 in the United States

Conservation Letters, Год журнала: 2022, Номер 15(1)

Abstract Achieving ambitious goals to conserve at least 30% of U.S. lands and waters by 2030 (“30 × 30”) will require a multiscale baseline understanding current protections, key decisionmakers, policy tools for moving forward. To help conservationists decisionmakers support the science‐based call address biodiversity climate crises, we analyze spatial patterns carbon in United States relative protected areas present typology classifying land contributions toward 30 goals. Analyses demonstrate that is achievable nationally, but heterogeneity highlights need tailored approaches from mix authorities federal, regional, state scales. Current protections rarely overlap with essential conserving imperiled species mitigating change. One‐fifth unprotected hotspots over 8% carbon‐rich face higher risk conversion 2050. In contrast, 3.6% 15.6% may experience exposure. Policy considerations making practical, substantive progress ecologically meaningful achievement goal include significant investments public private conservation.

Integrating climate‐change refugia into 30 by 30 conservation planning in North America

Frontiers in Ecology and the Environment, Год журнала: 2023, Номер 21(2), С. 77 - 84

Countries have set targets for conserving natural areas to mitigate biodiversity loss, such as the protection of 30% lands by 2030, commonly referred “30 30”. Yet strategic conservation planning align those with climate‐change refugia is lacking. We investigated feasibility achieving 30 in North America assessing proportions state/provincial/territorial land projected provide terrestrial and that are currently protected. also conducted a reserve selection prioritization identify priority complement current protected area network capture seven taxonomic groups. In America, <15% protected, but ample opportunity exists expand if warming limited 2°C. Beyond 2°C, however, majority will occur only at high latitudes elevations. Incorporation into efforts facilitate species persistence under climate change.

Integrating carbon stocks and landscape connectivity for nature‐based climate solutions

Ecology and Evolution, Год журнала: 2023, Номер 13(1)

Опубликована: Янв. 1, 2023

Actions to protect against biodiversity loss and climate change will require a framework that addresses synergies between these interrelated issues. In this study, we present methods for identifying areas important the implementation of nature-based solutions conservation by intersecting high-resolution spatial data carbon storage landscape connectivity. We explored congruence connectivity in Ontario, Canada examined effectiveness current protected coverage. found weak positive relationship stocks connectivity; however, our maps revealed large hotspots, with high values both indices, throughout boreal forest northern peatlands smaller, isolated settled landscapes south. Location hotspots varied depending on whether considered or soil carbon. Further, results show conserved Ontario only cover 13% highest Protection restoration maximize co-benefits would make significant contributions toward ambitious national targets reduce greenhouse gas emissions conserve biodiversity.
