Fisheries bycatch is the foremost threat to conservation of many marine species. Evaluation alternative management strategies can account for relative strength evidence, contribution achieving objectives, costs commercial viability, likelihood compliance and tradeoffs from multispecies conflicts. This study describes benefits limitations a complementary approach applying sequential mitigation hierarchy develop evidence-informed policy. Measures that avoid are considered before those minimize catch risk. These then followed by remediation interventions reduce fishing mortality sublethal impacts. Finally, direct, compensatory banking or in lieu fee-based offsets residual impacts were not possible avoid, remediate be implemented as last resort. However, offset activities socioeconomically unjust, some irreversible cannot offset. Air-breathing exposed wide range anthropogenic hazards across ontogenetic stages, presenting more options than fishes. Averted loss offsets, which foregone losses predicted occur had an intervention occurred, combination with true achieve at least equivalent gain contribute meeting broad, population- species-level objectives. Robust metrics needed determine equivalency, such reproductive value population between in-kind versus out-of-kind on-site offsite offsets. Bycatch guided promise ecological socioeconomic including going bycatch-neutral bycatch-negative through net biodiversity gain.

Financial Analysis of Habitat Conservation Banking in California

Habitat conservation banking is a policy instrument for conserving endangered species by providing financial incentives the landowners in United States. This aims to protect habitat, but little or no thought has been given its performance. A analysis of habitat banks (HCB) informs policymakers and biologists long-term success this future HCBs. paper evaluates 26 California calculating their Net Present Values (NPV). We do so compiling cost revenue data banks. The average annual operating HCBs was $42.78/acre (median: $22.58/acre), credit price from sale $6014.72/acre $553.65/acre). NPV $4205.90/acre at 4% rate return, indicating an overall positive return such easement instrument. However, only 14 out produced return. With inclusion land acquisition costs, three eight performed financially well. On brighter side, number increased with time. But there not enough evidence ascertain certainty revenues. right selection space (land costs can make break finances HCB) could encourage establish build confidence on those who may have discouraged lack knowledge fear losing due regulatory compliance conserve land. findings are helpful identifying lands prioritizing investments generate credits.

Precipitation, Vegetation, and Groundwater Relationships in a Rangeland Ecosystem in the Chihuahuan Desert, Northern Mexico

Hydrology, Journal Year: 2023, Volume and Issue: 10(2), P. 41 - 41

Published: Feb. 1, 2023

For this study, conducted in a semiarid (318 mm) rangeland setting the Chihuahuan Desert region northern Mexico, we evaluated seasonal and interannual variability of precipitation, vegetation, groundwater relations. Between 2012 2014, series soil water conservation practices (e.g., land imprinting, contour furrows, planting native shrub species) were several areas within 2500 ha study site. Since site has been gradually instrumented to monitor hydrologic variables, including rainfall, content, groundwater. The Normalized Difference Vegetation Index (NDVI) Infrared (NDII) vegetation indices used evaluate conditions between 2007 2021, before after treatment. Soil content began be monitored 2014 2016, respectively.

Flexibility Trade‐offs in Conservation Offsets

Conservation Biology, Journal Year: 2023, Volume and Issue: unknown

Published: July 10, 2023

Conservation offsets promise cost-effective conservation of biodiversity, especially under economic and environmental change, because they represent a more flexible approach to biodiversity conservation, allowing for the development ecologically valuable land provided that this is offset by restoration previously developed areas. The level flexibility determined trading rules. Lax rules allow flexibility, which promises cost savings, but will likely lead unintended loss biodiversity. I analyzed trade-off between costs ecological benefits (biodiversity conservation) in offsetting with an ecological-economic model considered three main types flexibility: spatial, temporal, ecosystem type. sought examine influence conditions on trade-offs. Large variation small habitat strongly increased activity reduced benefit. benefit was most sensitive spatial when short range interaction considered. At large range, delivered savings without overly reducing Risks time lags associated favored scheme credits are awarded initiation projects rather than their successful completion-given appropriate multipliers were chosen. Altogether, scarce resources, should be chosen carefully balancing costs.

Bundling of Ecosystem Services in Conservation Offsets: Risks and How They Can Be Avoided

Published: June 11, 2021

Conservation offsets are increasingly used as an instrument to conserve biodiversity and ecosystem services on private lands. Bundling (ES) in the market transactions saves costs but implies that only bundle of ES is conserved while individual may decline. This paper presents a simple model analysis conservation offset scheme identify conditions under which bundling can lead such undesired declines. As it turns out, these favoured by rarity well positive correlation between their abundance cost conservation. A rule proposed able avert Rather than sums or means ES, this focuses least abundant ES. Systematic variation parameters shows trading most effective those cases where likelihood losses highest.
