Optimal restoration of wildlife habitat in landscapes fragmented by resource extraction: a network flow modeling approach

Restoration Ecology, Journal Year: 2021, Volume and Issue: 30(5)

Published: Oct. 16, 2021

Non‐renewable resource extraction contributes greatly to degradation of wildlife habitats in boreal landscapes. In western Canada, oil and gas exploration have left a dense network linear disturbances (seismic lines) abandoned well pads that fragmented forest. Among multiple ecological effects, these increased predator access the preferred habitat some taxa, most notably woodland caribou, resulting population declines. Restoration seismic lines is critical activity improve recovery caribou populations. We present programming model optimally allocates restoration efforts maximize nearby undisturbed landscape. applied examine scenarios Cold Lake First Nations area northeastern Alberta, which includes but also areas active extraction. The depicts landscape as interconnected patches combines three flow sub‐problems. first sub‐problem enforces spatial connectivity remaining unrestored sites. second maximizes suitable from restored locations third ensures allocation activities few spatially contiguous projects possible. approach generalizable applicable assist planning other regions for taxa.

A novel non-redundant path method for the maximum covering species problem with connection requirements

Decision Analytics Journal, Journal Year: 2024, Volume and Issue: 10, P. 100437 - 100437

Published: Feb. 28, 2024

This paper proposes a novel model formulation for the Maximum Covering Species Problem that incorporates spatial connectivity requirements. model, called Connected Problem, enforces structural and relies on knowledge of induced paths, or what we call non-redundant paths in conservation planning. A tabu-search-based algorithm is proposed to list all which then serve as input Problem. Since this approach path-related data, it offers several advantages over other approaches area research, such heuristic adaptation embedding time-dynamic concepts. Linearization aspects are discussed strength planning demonstrated computational study.

ENHANCING ECOLOGICAL CORRIDORS IN RURAL AREAS AND IMPLICATIONS FOR LANDSCAPE PLANNING AND MANAGEMENT IN LESZNO COMMUNE IN CENTRAL POLAND

Acta Scientiarum Polonorum Formatio Circumiectus, Journal Year: 2024, Volume and Issue: 23(1), P. 19 - 35

Published: Feb. 19, 2024

Aim of the study: The paper presents research aimed at recognition, evaluation, and improvement ecological connectivity within area Leszno commune area, focusing on establishment new corridors enhancement existing ones in rural adjacent to forest ecosystems, part Kampinoska Primeval Forest belonging Kampinoski National Park, Central Poland, middle European Lowland. Material methods: desk consisted two sections: prior field study after study. During research, located south parts municipality was observed documented. original methodical approach has been used, applying division into landscape units for further detailed analysis, enabling precise addressing recommendations. By assessing vegetation cover, dominant levels, their continuity beyond agricultural units, important insights value each unit were gained. Results conclusions: Negative impact roads identified as a major challenge. importance along habitat passages mitigating isolation recognized. Enhancing cover creating various types green – linear, stepping stones, connecting forests, also roads, while maintaining zone free high directly next road (due requirement visibility drivers), are proposed measures mitigate impacts, preserve connectivity, promote movement species.

Trimming the hedges in a hurricane: Endangered Species lack research on the outcomes of conservation action

Published: April 30, 2024

Given widespread biodiversity declines, there is an urgent need to ensure that conservation interventions are working. Yet, evidence regarding the effectiveness of actions often lacking. Using a case study 208 terrestrial species listed as Endangered in Canada, we conducted literature review collate base on to: 1) explore outcomes documented for each species; and 2) identify knowledge gaps. Action-oriented research constituted only 2% all across target species, 56% found no investigating actions. Protected areas, habitat creation, artificial shelter, alternative farming practices were broadly beneficial most which these assessed. Habitat restoration frequently studied, but almost 38% harmful, ineffective, or demonstrated mixed results. The prescribed burns, timber harvesting approaches vegetation control was examined greatest number yet 17-30% negative effects. Our synthesis yielded dataset can be implemented aid recovery planning at risk, highlighted alarming gaps merit further investigation.
