Trail use is growing globally. Managers confront the classic dilemma of protecting ecological integrity and providing enriching experiences. They concomitantly face the imperative for sustainability—contemporarily characterized by complexity, uncertainty, conflict, and change. Heightened levels of visitation are cause for immense concerns due to adverse impacts to the environment as well as visitor experiences. COVID-19 exacerbates these challenges as heightened levels of visitation are occurring, while managers simultaneously face decreases in conservation funding, and restrictions on protected area operations. Participatory monitoring and evaluation (PM&E) is an emerging in- novation to collaboratively address social-ecological challenges, such as issues as- sociated with trail use. This research is concerned with exploring the influences of engaging in a PM&E process on stakeholder perceptions of key performance indicators (KPIs) for trails. This study compares stakeholder perceptions of KPIs for trails before and after a PM&E workshop at the Niagara Glen Nature Reserve in Ontario, Canada. Results show that PM&E can facilitate consensus among stakeholders regarding the overall goals of management and associated KPIs for environmental management planning. Stakeholders were shown to experience a real change in their perceptions of KPIs. The PM&E process studied show that participants became more conscious of the wider social realities as well as their perceptions of trail management. The study has important implications for managers concerned with trails and sustainability, including building consensus among key stakeholders to reach management goals, enhancing localized decision making, and building capacity for management towards sustainability. Trails, as well as the wider community can ultimately benefit from participatory approaches to environmental management. Consensus-building through PM&E works to enhance decisions that account for a diversity of perspectives. Stakeholder participation in trail management increases the likelihood that local needs and priorities are met, while allowing stakeholders to build capacity and learn to effectively manage their environments. Furthermore, positive perceptions from being meaningfully involved in PM&E can ensure the support of constituents, which is imperative for the long-term success of management planning.

Land-Use Cover Changes (LUCCs) are one of the main problems for the preservation of landscapes and natural biodiversity. Protected Areas (PAs) do not escape this threat. Poland is among the European leaders in terms of the variety of landscapes and the share of an area designated as a protected area. However, as many as 78% of the habitats have poor or bad conservation status based on EEA reports. This article analyzes the LUCCs between 2000 and 2018 in various types of the Polish legal forms of nature protection areas and the European Natura 2000 network within the country. The research material was: the data of Corine Land Cover (CLC), the Central Register of Nature Protection Forms, and high-resolution layers, such as HRL and orthophotos. The results were compiled according to the CLC class and forms of protection. The matrix of transformations showed that the most frequently transformed CLC class was 312 (coniferous forest). It was transformed into class 324 (transitional woodland shrubs). The changes in PAs were usually smaller than in the surrounding buffer zones, which may indicate their effectiveness. The exception was the areas of the European Natura 2000 network. The scale of land-cover flows (LCFs) changed within particular forms of protected areas, though afforestation and deforestation predominating in all area types. National reserves and parks were the most stable in terms of land cover structures. However, human settlements increased around the protected areas, potentially increasing threats to their ecological integrity.

Abstract Indigenous Peoples’ (IP) stewardship has helped conserve biodiversity and maintain healthy ecosystems worldwide. Among many challenges to this role are mounting pressures from industrial development. By assessing the current ecological condition of Indigenous lands with their potential for future industrial development, we show that the ecological integrity of 22% (8.6 million km2) of Indigenous lands is highly threatened across five continents and 37 countries. We further find that the risk to Indigenous lands is greatest across West and Central Africa because of their high ecological threat and greater obstacles for Indigenous Peoples to realize self-determined and culturally-responsive development outcomes. Using a novel national-level framework that examines the security of IP’ rights and authority over their lands, their capacity to engage in decision-making, and support for facilitating sustainable development, we highlight potential challenges and opportunities for strategic investments and interventions to help IP safeguard their futures and rights, as well as the ecological integrity of their lands.

The mining industry is one of the leading sectors providing economic benefit to the community. However, mining minerals inevitably affect the ecosystem function of the land, thereby reducing ecological services provided to mankind. Soil remediation is done to restore ecological integrity while mitigating degradation processes. Thus, this study was conducted to determine the chemical properties of abandoned mine soil and to determine the effects of oil palm residues on the growth performance of abaca (Hybrid 7) grown in mined soil under nursery conditions. This study was arranged in a completely randomized design (CRD) with five treatments and four replications, namely, T1 - Mined Soil Alone, T2 - Garden Soil Alone, T3 - Mined soil + Oil Palm Sludge, T4 - Mined Soil + Oil Palm Empty Fruit Bunch (EFB) Biochar, T5 – Mined Soil + Oil Palm Vermicast. Chemical analysis of mined soil revealed extreme acidic soil condition, low organic matter, CEC, N, K, and high P content relative to soil nutrient sufficiency criteria. Mined soil contained 0.347 mg/kg Cd and 0.230 mg/kg Pb which are within the tolerable limit of 2.00 mg/ kg for Cd and 300 mg/kg (Pb), respectively. Application of oil palm residues in mined soil can significantly improve the morphology and dry matter yield performance of hybrid 7 abaca seedlings. Plants grown in mined soil amended with oil palm residues were taller, larger pseudostem girth with more and bigger functional leaves, and had a higher survival rate compared to those grown in soil derived from the abandoned mining area. Abaca plants grown with amendments had accumulated higher dry matter. Oil palm residues particularly vermicast has greater potential as soil amendment under degraded mined in Mawab, Davao de Oro.

Contextualization: Colombia has experienced multiple land-cover changes derived from socio-economic policies that have reduced the high biodiversity of the country.  Knowledge gap: In the Orinoquía region, the pressure to expand the agricultural frontier is increasing, without considering the importance of its natural resources.  Purpose: This paper aimed to analyze the land-cover variations associated with agricultural practices, in the department of Vichada, with a special interest in vulnerable ecosystems, such as the Bita’s river basin, using Geographic Information System [GIS] analysis of historical images taken by a remote sensor from the United States Geological Service [USGS] Earth Explorer portal.  Methodology:  Documental review and an analysis of satellite images from 1985 to 2017.  Results and conclusions: The results showed that in Vichada, during a 32-year period, there was a transition from forest to cropland and pastures, in which 60% of the forest cover got lost. Moreover, areas of natural savannas were also replaced with pastures for livestock production. These land-cover changes were associated with government policies that fomented illegal occupation of land, monocultures, and non-native plantation forests. Bita’s river basin also lost a significant part of forest cover because of agribusiness development in the municipality of Puerto Carreño (Vichada). These land-cover changes have an impact on the ecological integrity of significant ecosystems and in their functionality in the region, that is why, conservation measures must be implemented.

Droughts are complex and gradually evolving conditions of extreme water deficits which can compromise livelihoods and ecological integrity, especially in fragile arid and semi-arid regions that depend on rainfed farming, such as Kitui West in south-eastern Kenya. Against the background of low ground-station density, 10 gridded rainfall products and four gridded temperature products were used to generate an ensemble of 40 calculations of the Standardized Precipitation Evapotranspiration Index (SPEI) to assess uncertainties in the onset, duration, and magnitude of past droughts. These uncertainties were driven more by variations between the rainfall products than variations between the temperature products. Remaining ambiguities in drought occurrence could be resolved by complementing the quantitative analysis with ground-based information from key informants engaged in disaster relief, effectively formulating an ensemble approach to SPEI-based drought identification to aid decision making. The reported trend towards drier conditions in Eastern Africa was confirmed for Kitui West by the majority of data products, whereby the rainfall effect on those increasingly dry conditions was subtler than just annual and seasonal declines and greater annual variation of rainfall, which requires further investigation. Nevertheless, the effects of increasing droughts are already felt on the ground and warrant decisive action.

Open woodlands dominated by shortleaf pine (Pinus echinata Mill.) and oak are historically an important component of the landscape across the southeastern United States. These ecosystems support numerous wildlife species, many of which have declined in recent years as the amount and condition of their habitat have declined. Land managers and private landowners need guidance on how to efficiently and accurately quantify the condition and wildlife habitat value of the pine stands that they manage. Here we provide a set of rapid assessment metrics, based on NatureServe’s ecological integrity assessment (EIA) method, to (a) identify exemplary tracts that provide the best habitat for key wildlife species, and (b) monitor restoration efforts to assess progress toward the improved quality of existing tracts. To ensure an ecologically appropriate scaling of metrics, we distinguished six types of shortleaf pine–oak woodland: A.—Interior Highlands shortleaf pine–oak (including A.1—shortleaf pine–oak forest and woodlands; A.2—shortleaf pine–bluestem woodlands); B—montane longleaf pine–shortleaf pine woodlands; C—southern Appalachian pine–oak woodlands; D—West Gulf coastal plain shortleaf pine–oak woodlands; and E—southeast coastal plain and Piedmont shortleaf pine–oak woodlands. We relied on a narrative conceptual model and peer review-based indicator selection to identify a core set of 15 stand-level metrics (two were optional). Individual assessment points (thresholds) and ratings (Excellent, Good, Fair, and Poor) were developed that were sensitive to the distinct attributes of each of the five shortleaf pine–oak and Appalachian pine–oak types. Values for the metrics can all be collected using rapid field methods, such as using basal area prisms and ocular (visual) estimates of cover. Protocols for the consistent application of these EIA methods are provided. A case study is presented from the Cherokee National Forest in Tennessee. These methods provide improved and rapid EIA metrics for all shortleaf pine–oak ecosystems in the southeastern US to help guide conservation-minded landowners in assessing the biodiversity and priority wildlife values of shortleaf pine–oak and southern Appalachian pine–oak ecosystems.
