Ecological Indicators, Journal Year: 2023, Volume and Issue: 148, P. 110121 - 110121

Published: March 14, 2023

Protected areas (PAs) play a key role in mitigating ecological crises. Currently, priority protected (PPAs) focus on biological conservation, and few studies have considered the connectivity between patches. Few formulated future conservation measures from two dimensions of security pattern (ESP) reserve effectiveness. To fill this gap, study use ESP to identify that meet objectives. We take Wuhan metropolitan area as research area. constructed framework for formulating development plans based areas. The complete method system, we focused construction evaluation index system landscape connectivity. Then, effectiveness PAs could be evaluated, PPAs identified. results showed there were five isolated among existing PAs. Moreover, total was 9328.91 km2, they had high value. Due low protection rate PPAs, are not main target PAs; thus, new According our plan, with different classes will achieve functions work. Our focuses achieving sustainable formulates environmental land planning balance urban development. It can provide information support realization 2030 vision

Evaluating the ecological security of ecotourism (EES) in protected areas is critical because these play a vital role protecting biodiversity and natural resources. This study evaluated EES status Central Alborz Protected Area (Northern Iran), based on Driver, Pressure, State, Impact, Response (DPSIR) model. We developed comprehensive list 59 indicators for DPSIR model employed an Analytical Network Process (ANP) to determine indicator weights harnessing opinion experts which are most influential. approach facilitated identification regions with highest vulnerability, notably northern western sectors our area along boundary between Tehran Mazandaran provinces.

Transboundary ecological network identification for addressing conservation priorities and landscape ecological risks: Insights from the Altai Mountains

Ecological Indicators, Journal Year: 2023, Volume and Issue: 156, P. 111159 - 111159

Published: Oct. 27, 2023

Insufficient conservation measures and intense human disturbances gave rise to severe landscape ecological risks (LERs) in transboundary areas, highlighting the significance of networks maintain functions integrity. However, previous studies mainly concerned inner regions a country, various risk factors remain be incorporated into network identification clarify priorities for conservation. In this study, we took Altai Mountains areas China, Kazakhstan, Russia, Mongolia as study area, identified by integrating LER assessment, ecosystem service evaluation circuit theory. The results showed that was spatially heterogenous with salient exposure China Mongolia, disturbance aggregated Russia. included sources an area 1.6 × 105 km2 corridors total length 1.1 104 km, densely distributed Russia Kazakhstan. proportion not covered existing protected reached 53.8 %, indicating further We put forward management zoning different grades better support actions on sources. Furthermore, suggestions were proposed conserve typical landscapes Mountains. can facilitate plannings policies Simultaneously, it also provides reference effective risked ecosystems other areas.

Habitat and connectivity‐based conservation strategies for the vulnerable Lorestan newt (Neurergus kaiseri) in the Zagros Mountains, Iran

Journal of Wildlife Management, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Abstract The Lorestan newt ( Neurergus kaiseri ) is a vulnerable amphibian endemic to the Zagros Mountains in Iran. This study aimed identify core habitats, assess potential dispersal corridors, and evaluate effectiveness of current conservation efforts. Ensemble species distribution models predicted suitable habitat across newt's range, with annual precipitation temperature as most influential factors. Connectivity simulations revealed critical primarily concentrated northwestern region, that spanned 2,233.43 km², none which fell within designated protected areas. Corridor analysis identified viable pathways between northern southern populations, but only 2.77% corridor network was protected. Roads dams frequently intersected putative posing significant fragmentation threats. These results underscore urgent need for expanded efforts, including establishment new areas measures mitigate fragmentation, ensure connectivity long‐term viability populations. Our findings provide valuable insights guide future strategies this endangered species.

As significant ecosystem disturbances flooding events are expected to increase in both frequency and severity due climate change, underscoring the critical need understand their impact on biodiversity. In this study, we employ advanced remote sensing machine learning methodologies investigate effects of biodiversity, from individual species broader ecological communities. Specifically, utilized Sentinel-1 synthetic aperture radar (SAR) images an ensemble machine-learning algorithms derive a flood susceptibility indicator. Our primary objective is potential benefits incorporating susceptibility, as proxy for risk, into distribution models (SDMs). By doing so, aim improve performance SDMs gain deeper insights consequences floods Within biodiverse landscape Zagros Mountains, crucial Irano-Anatolian biodiversity hotspots, examined sensitivity mammals, amphibians, reptiles' distributions flooding. analysis compared that combined with variables against relying solely variables.

Published: Feb. 1, 2024

With land use change rapidly increasing in Asia, conservation prioritization has emerged as an important tool identifying critical landscapes for biodiversity to safeguard them from human pressures. In Peninsular Malaysia, the Malaysian Nature Society (MNS/BirdLife Malaysia) developed a set of Criteria identify Important Hornbill Landscapes (IHLs) – hornbill hotspots which are priority sites Malaysia and serve inform planning action. Application so far been restricted thus this study, we adapt it Sarawak, state Borneo that supports 80% species diversity country. We expand on methodology using Maximum Entropy Species Distribution Modelling (MaxEnt), validate Criteria's applicability potential IHLs Sarawak. Our data sources included literature reviews, citizen science databases interviews. Expectedly, survey effort was spatially biased. identified eight IHLs, mostly concentrated eastern across national parks, wildlife sanctuaries forest management units. Existing published distribution habitats Sarawak corroborated with our MaxEnt outputs aligned results IHL Criteria-based assessment, validating latter supporting its additionally six based confirmed value pairing such exercise. To knowledge, study not only demonstrates significance combining identification, but also represents first application outside Malaysia. findings can, therefore, case future applications potentially other parts Asia.

Threats caused by human activities have reduced the quantity and quality of wildlife habitats connectivity. This research seeks to protect habitat biodiversity creating a network high that remained. Therefore, it is very necessary know about dynamic effects changes in landscape pattern on habitat, because helps preserve biodiversity, guarantee ecological security, environmental sustainability. In present study, systematic process was used design services comprising hotspots corridors arid semi-arid ecosystems eastern Iran, South Khorasan Province. this process, first modeled using InVEST software, then data mining methods were identify their spatial distribution. next step, extracted based circuit theory Circuitscape software. ultimate graph concept connectivity evaluated. The results construction showed 8% 6% total area study included key patches corridors, respectively. On other hand, overlapping components with conserved areas free or non-conservation make up significant amount (49.18% patch 80.02% corridor). These reveal existence protection potential can help updating new boundaries conservation areas. Also, composite indices dPC dIIC could determine importance each network's evaluating network, so application show priority options land managers for protecting network. general, proposed be planning sustainable networks, identifying patterns constructing networks lands similar climates, changing wisely reviewing boundaries.
