The ‘Paper Park Index’: Evaluating Marine Protected Area effectiveness through a global study of stakeholder perceptions

Governments around the world are increasingly committed to reaching terrestrial and marine conservation goals. But achieving such commitments is challenging, and conservation targets that are reached on paper, e.g., in terms of square kilometers protected, can be misleading. Designating Marine Protected Areas (MPAs) does not guarantee achieving marine conservation goals, and so-called ‘paper parks,’ i.e., MPAs that are legally designated but ineffective, are common.

National-level evaluation of a community-based marine management initiative

Community-based approaches to conservation and natural resource management are considered essential to meeting global conservation targets. Despite widespread adoption, there is little understanding about successful and unsuccessful community-based practices because of the challenges of designing robust evaluations to estimate impacts and analyse the underlying mechanisms to impact. Here we present findings from a national scale evaluation of the ‘locally managed marine areas’ network in Fiji, a marine community-based management initiative.

FINAL REPORT - Seabird Survey of Aleipata Offshore Islands, Samoa. 24-26 October 2022

The Aleipata group of offshore islands have been identified as one of eight Key Biodiversity Areas (KBAs) in Samoa. They are located at the south-eastern end of Upolu Island at 14o3’447.28”S, 171o25’23.84”W (Nu’utele) and 14o4’22.11”S and 171o24’36.17”W (Nu’ulua) offshore. This project updates population estimates and establish baseline data and information on breeding seabirds of the Aleipata offshore islands and investigate the feasibility of future tracking studies of some species.

O Le Pupu Pu'e National Park (Ramsar Site) Management Plan 2020-2030

O Le Pupu-Pu'e National Park was the first Park established in Samoa at a time when the environment movement and concerns for our unique biodiversity and natural features was still only a passing thought. It has been forty-two years since the OLPPNP was established and the Park remains one of the as one of the few areas on Upolu island that has extensive protection from the ridge to reef.

Global Protected Areas as refuges for amphibians and reptiles under climate change

Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated distributional data for >14,000 (~70% of) species of amphibians and reptiles (herpetofauna) to perform a global assessment of the conservation effectiveness of PAs using species distribution models. Our analyses reveal that >91% of herpetofauna species are currently distributed in PAs, and that this proportion will remain unaltered under future climate change. Indeed, loss of species’ distributional ranges will be lower inside PAs than outside them.

The past as a lens for biodiversity conservation on a dynamically changing planet

We are in the midst of a major biodiversity crisis, with deep impacts on the functioning of ecosystems and derived benefits to people (1, 2). But we still have time to pull back. To do so, it is imperative that we learn from plants’ and animals’ past actions (3, 4). Conservation biology, ecology, and paleontology all emphasize that natural systems must exhibit resilience and dynamic responses to rapid environmental changes (3, 5, 6). Both climate and land-use change have accelerated over the past decades, underscoring the urgency for increased understanding and action (7–9).

Enhanced regional connectivity between western North American national parks will increase persistence of mammal species diversity

Many protected areas worldwide increasingly resemble habitat isolates embedded in human-modifed landscapes. However, establishing linkages among protected areas could signifcantly reduce speciesloss rates. Here we present a novel method having broad applicability for assessing enhanced regional connectivity on persistence of mammal diversity. We combine theoretically-derived species relaxation rates for mammal communities with empirically-derived pathways.

Harnessing island–ocean connections to maximize marine benefits of island conservation

Islands  support  unique  plants,  animals,  and  human societies found nowhere else on the Earth. Local and global stressors threaten the persistence of island ecosystems, with invasive species being among the most damaging, yet solvable, stressors. While the threat of invasive terrestrial mammals on island flora and fauna is well recognized, recent studies have begun to illustrate their extended and destructive impacts on adjacent marine environments.

Machine learning prediction of connectivity, biodiversity and resilience in the Coral Triangle

Even optimistic climate scenarios predict catastrophic consequences for coral reef ecosystems by 2100. Understanding how reef connectivity, biodiversity and resilience are shaped by climate variability would improve chances to establish sustainable management practices. In this regard, ecoregionalization and connectivity are pivotal to designating effective marine protected areas.

Protected Area Network Expansion and Management: Economics to improve conservation outcomes

This paper identifies the Dasgupta Review’s key points about the role of protected areas (PAs) in conserving nature. Using these factors as a foundation, this paper explores how economists can conduct analyses that improve PA decisions and promote both biodiversity conservation and ecosystem service provision. People’s interactions with PAs should be considered when making design, management, and restrictions decisions about PAs because those interactions are critical to determining the threats to biodiversity within PAs and the benefits produced by PAs.
