Camera captures return of rare Aussie predator believed extinct across 70km landscape
Over five years after cameras were set up within a sprawling Western Australian landscape, an elusive “chuditch” has…

This article describes a comprehensive framework for soil organic carbon density (SOCD, kg/m3) modeling and mapping, based on spatiotemporal random forest (RF) and quantile regression forests (QRF). A total of 45,616 SOCD observations and various Earth observation (EO) feature layers were used to produce 30 m SOCD maps for the EU at four-year intervals (2000–2022) and four soil depth intervals (0–20 cm, 20–50 cm, 50–100 cm, and 100–200 cm). Per-pixel 95% probability prediction intervals (PIs) and extrapolation risk probabilities are also provided. Model evaluation indicates good overall accuracy (R2 = 0.63 and CCC = 0.76 for hold-out independent tests). Prediction accuracy varies by land cover, depth interval and year of prediction with the worst accuracy for shrubland and deeper soils 100–200 cm. The PI validation confirmed effective uncertainty estimation, though with reduced accuracy for higher SOCD values. Shapley analysis identified soil depth as the most influential feature, followed by vegetation, long-term bioclimate, and topographic features. While pixel-level uncertainty is substantial, spatial aggregation reduces uncertainty by approximately 66%. Detecting SOCD changes remains challenging but offers a baseline for future improvements. Maps, based primarily on topsoil data from cropland, grassland, and woodland, are best suited for applications related to these land covers and depths. We recommend that users interpret the maps in conjunction with local knowledge and consider the accompanying uncertainty and extrapolation risk layers.

In some cases, managing an established invasive species may do more harm to an ecosystem than allowing the invader to persist. Given limited resources available to land managers and the realities of conservation triage, we recognized the need for systematic guidance for management decisions made at the “late end” of the invasion curve. We gathered an interdisciplinary group of experts and practitioners to address the question of “under what circumstances is the active management of an established aquatic invasive species warranted?” Our working group identified three key dimensions to this question: (1) the efficacy of available management options; (2) the net benefits of management actions weighed against the null scenario of no control; and (3) the socio-ecological context that defines management goals, a manager’s ability to achieve said goals, and perceptions of management outcomes. These considerations were used to structure a consensus decision tree that supports a multi-criteria approach to decision-making. Our approach promotes interdisciplinarity and systems thinking and emphasizes the need to consider costs and benefits comprehensively, for example by considering the persistence or reversibility of impacts from both the invasive species and from efforts to suppress or eradicate it.

"First, #hubris in human attitudes toward natural systems is an impediment to progress" demanding a "shift from the idea that ‘‘humans can conquer nature’’ to ‘‘humans coevolve with nature’’"
"Second, [...] #local economic decisions are increasingly shaped by conditions and processes half a world away"
"Third, [...] management systems should be dynamic, but #inertia tends to dominate the social, political, and economic structures involved in many aspects of #NaturalResourceManagement" [2]
Thank you thank you Courtney Ellis for your terrific work in guiding my babbling through an interesting conversation on #ecology, #EcosystemServices #birding #NaturalResourceManagement, etc.

Listen to this episode from The Thing with Feathers: birds and hope with Courtney Ellis on Spotify. This week: Courtney talks to Tim O'Connell about ecology, conservation, cultural beliefs about eagles and vultures, and Tim offers up the best bobolink impression we've ever heard. The Thing with Feathers is birds, birding, and hope with an obsessive newbie birder and a wide range of experts and special guests. New episodes every Monday!
