Predicting the distribution of invasive weeds under climate change is important for the early identification of areas that are susceptible to invasion and for the adoption of the best preventive measures. Here, we predicted the habitat suitability of 16 invasive weeds in response to climate change and land cover changes in South Korea using a maximum entropy modeling approach. Based on the predictions of the model, climate change is likely to increase habitat suitability. Currently, the area of moderately suitable and highly suitable habitats is estimated to be 8877.46 km2, and 990.29 km2, respectively, and these areas are expected to increase up to 496.52% by 2050 and 1439.65% by 2070 under the representative concentration pathways 4.5 scenario across the country. Although habitat suitability was estimated to be highest in the southern regions (<36° latitude), the central and northern regions are also predicted to have substantial increases in suitable habitat areas. Our study revealed that climate change would exacerbate the threat of northward weed invasions by shifting the climatic barriers of invasive weeds from the southern region. Thus, it is essential to initiate control and management strategies in the southern region to prevent further invasions into new areas.

Aim: Habitat loss has been the greatest historical driver of species extinctions. A recent global trend toward retirement of marginally productive agricultural lands presents opportunities to reclaim critical habitat for endangered species. We examine habitat restoration opportunities in the context of historical sources of habitat loss, including agriculture, development, habitat fragmentation, and invasive-species-mediated climatic niche contraction. Location: California’s San Joaquin Desert (SJD) is one of the world’s most agriculturally productive landscapes. Fragments of remnant habitat serve as habitat for 34 threatened and endangered species. Retirement of agricultural land in the SJD is being driven by climate change, groundwater salinization, and historical groundwater overdraft—even as unmitigated loss of virgin habitat continues. Methods: To promote efficient habitat protection and restoration, we conducted a quantitative assessment of habitat suitability, habitat loss, climatic niche stability, projected effects of climate change, and reintroduction opportunities for an umbrella species, the endangered blunt-nosed leopard lizard (Gambelia sila). Results: Analyses indicate that G. sila habitat overlaps with occurrence records for 128 vulnerable species and that its habitat is broadly representative of the habitat of other vulnerable species in the SJD. We document an apparent climatic niche contraction for G. sila and associated range contraction away from more mesic margins of the historical distribution, apparently driven by introduction of exotic grasses and forbs. We use habitat suitability models, in conjunction with modern and historical land use maps, to estimate historical and modern rate of habitat loss to development and fragmentation. We use NASA fallowed area maps to identify 610 km2 of fallowed or retired agricultural land with high potential to be restored as habitat. We discuss conservation strategies in light of anticipated climate change and potential for habitat restoration. Main Conclusions: In the midst of multiple sources of historical and ongoing habitat loss, farmland retirement presents an opportunity to recover large amounts of endangered species habitat.

Abstract Background The oak tree (Quercus aegilops) comprises ~ 70% of the oak forests in the Kurdistan Region of Iraq (KRI). Besides its ecological importance as the residence for various endemic and migratory species, Q. aegilops forest also has socio-economic values—for example, as fodder for livestock, building material, medicine, charcoal, and firewood. In the KRI, Q. aegilops has been degrading due to anthropogenic threats (e.g., shifting cultivation, land use/land cover changes, civil war, and inadequate forest management policy) and these threats could increase as climate changes. In the KRI and Iraq as a whole, information on current and potential future geographical distributions of Q. aegilops is minimal or not existent. The objectives of this study were to (i) predict the current and future habitat suitability distributions of the species in relation to environmental variables and future climate change scenarios (Representative Concentration Pathway (RCP) 2.6 2070 and RCP8.5 2070); and (ii) determine the most important environmental variables controlling the distribution of the species in the KRI. The objectives were achieved by using the MaxEnt (maximum entropy) algorithm, available records of Q. aegilops, and environmental variables. Results The model demonstrated that, under the RCP2.6 2070 and RCP8.5 2070 climate change scenarios, the distribution ranges of Q. aegilops would be reduced by 3.6% (1849.7 km2) and 3.16% (1627.1 km2), respectively. By contrast, the species ranges would expand by 1.5% (777.0 km2) and 1.7% (848.0 km2), respectively. The distribution of the species was mainly controlled by annual precipitation. Under future climate change scenarios, the centroid of the distribution would shift toward higher altitudes. Conclusions The results suggest (i) a significant suitable habitat range of the species will be lost in the KRI due to climate change by 2070 and (ii) the preference of the species for cooler areas (high altitude) with high annual precipitation. Conservation actions should focus on the mountainous areas (e.g., by establishment of national parks and protected areas) of the KRI as climate changes. These findings provide useful benchmarking guidance for the future investigation of the ecology of the oak forest, and the categorical current and potential habitat suitability maps can effectively be used to improve biodiversity conservation plans and management actions in the KRI and Iraq as a whole.
