Forest landscape restoration (FLR) is purported to achieve socio‐ecological outcomes in addressing the interlinked crises of deforestation and land degradation, biodiversity loss, climate change. While several instruments exist substantiate progress toward such effectiveness FLR interventions, various challenges hinder monitoring. This study uses a proposed analytical framework that articulates elements monitoring feasibility examine realistic application convenience instruments, focusing on Africa, where continental‐level flagships are scaling up actions. We applied critical content analysis guided by our lens secondary data collected from top‐down bottom‐up instruments. A survey was also used explore level knowledge identify tools guiding frameworks practitioners, which we analyze using descriptive statistics. Our reveals 34 indicators spanning biophysical, socio‐economic, institutional realms, along with 196 related metrics. The strong emphasis biophysical metrics relative socio‐economic ones reflects unbalanced attention sustainability dimensions. identified 39 indicates most require essential (super)infrastructural capacities, appropriate knowledge, tailored skills for their effective use. Confirming this, low awareness use these three cited limiting reasons being inadequate funding, infrastructure deficits, technical expertise. Overall, results reaffirm need pragmatic, low‐cost, accessible advance offer actionable suggestions some challenges.

Although species are being lost at alarming rates, previous research has provided conflicting results on the extent and even direction of global biodiversity change local scale. Here, we assessed ability to detect trends using richness how it is affected by number monitoring sites, sampling interval (i.e. time between original survey re‐survey site), measurement error (error richness), spatial grain (a proxy for taxa mobility) biases site‐selection biases). We use PREDICTS model‐based estimates as a real‐world distribution randomly selected sites calculate trends. found that while network with hundreds could in within 30‐year period, detecting doubled decade, increased 10‐fold three years yearly were undetectable. Measurement errors had non‐linear effect statistical power, 1% reducing power slight margin 5% drastically reliably any trend. The was also related grain, making harder sampled smaller plot sizes. Spatial not only reduced negative but sometimes yielded positive conclude accurate may simply be unfeasible current approaches. suggest representative implemented national level, combined models accounting biases, can help improve our understanding change.

Abstract Passive acoustic monitoring (PAM) has gained increasing popularity to study behaviour, habitat preferences, distribution and community assembly of birds other animals. Automated species classification algorithms like ‘BirdNET’ are capable detecting classifying avian vocalizations within extensive audio data, covering entire assemblages. PAM reveals substantial potential for biodiversity that informs evidence‐based conservation. Nevertheless, fully realizing this remains challenging, especially due the issue false‐positive detections. Here, we introduce an optimized thresholding framework, which incorporates contextual information extracted from time‐series automated detections (i.e. covariates on quality quantity species' measured at varying time intervals) improve differentiation true false positives. We verified a sample BirdNET per modelled species‐specific thresholds using conditional inference trees. These were designed minimize while maximizing preservation positives in dataset. tested framework large dataset (5760 h 60 sites) recorded over breeding season. Our results revealed considerable interspecific variability precision (percentage positives) raw data. approach achieved high (≥0.9) 70% 61 detected species, solely relying confidence scores only 31% species. Conservative universal (not species‐specific) reached 48% outperformed previous approaches enhanced comparability bird analyses. By incorporating detections, was substantially improved. may enhance straightforward application research, landscape planning

Abstract Biodiversity loss has reached critical levels partly due to anthropogenic habitat and degradation. These landscape changes are damaging as they can fragment species distributions into small, isolated populations, resulting in limited gene flow, population declines reduced adaptive potential. Genetic rescue, the translocation of individuals increase genetic diversity ultimately fitness, produced promising results for fragmented populations but remains underutilized a lack long‐term data monitoring. To promote better understanding rescue its potential risks benefits over short‐term, we reviewed analysed published attempts identify whether increases following translocation, if this change is associated with increased fitness. Our review identified 19 studies that provided fitness from before after translocation; majority these were on mammals, included experimental, natural conservation‐motivated translocations. Using Bayesian meta‐analytical approach, found average, post translocations, although there some exceptions trend. Overall, was positive predictor cases relationship extended three generations post‐rescue. suggest single have lasting benefits, support another tool facilitate conservation success. Given number data, echo need monitoring post‐translocation understand also limit long‐term.

Bioavailable strontium isotope ratios ( 87 Sr/ 86 Sr) distribution across the landscape mainly follow underlying lithology, making Sr baseline maps (isoscapes) powerful tools for provenance studies. has already been used in Eastern Canada (EC) to track food and human remains origins, or reconstruct animal mobility. While bioavailable isoscapes EC can be extrapolated from global datasets using random forest modelling (RF), no regionally calibrated isoscape exists. Here, we produce a by analysing plants collected at 136 sites EC, incorporating updated geological variables applying novel ensemble machine learning (EML) framework. We generated compared traditional RF EML approaches. Adding local dataset significantly improved model prediction with drastic increase of predicted increased spatial uncertainty northern Canadian craton. produced similar predictions but tighter distribution.

Abstract The high demand for information on how coral reefs are changing often exceeds the capacity of scientific community to deliver data necessary meet this need. However, given degraded state and poor prognosis their recovery, it is reasonable ask whether reef monitoring should continue. Using my experiences from a 37-year study in US Virgin Islands, I highlight that conveys reefs, underscore interpretation ecological trends matures with increasing longevity records. Because past an imperfect predictor future, remains important endeavor. It offers only opportunity understand will continue change, connect patterns change processes causing them occur, create opportunities management best ensure future.
