Protected areas (PAs) are considered as a globally accepted strategy for biodiversity conservation that demonstrates the difficulties in meeting the proposed objectives; therefore, different conservation schemes are promoted to integrate the design of interfaces that favor the exchange of knowledge among different sectors, systems and stakeholders. The objective of this study was to characterize challenges regarding the protection of natural protected areas and other biodiversity conservation schemes in Tamaulipas, Mexico. This paper analyzed 39 areas with some form of protection status in addition to the 70 national and international designations that are part of them. A document review and 13 semi-structured interviews were conducted with experts from the public, private, academic, and civil society sectors. The data were analyzed from a qualitative perspective using ATLAS.ti 9 software. The results show the overlapping of protection schemes in priority areas; the lack of policies and mechanisms that integrate the different schemes to facilitate the exchange between stakeholders; and regulatory, structural, governance, management, participation, and operational gaps, as well as the absence of comprehensive and long-term work. The importance of and challenges in articulating the different schemes and visions to achieve effective biodiversity conservation are evident.

Access to natural resources has changed over the years in Zimbabwe. At least three broad periods of biodiversity conservation, utilisation, and access can be identified in the country, namely, the precolonial, colonial, and postindependence periods. This paper reviews the relationships between human livelihoods and biodiversity conservation in the rural areas of Zimbabwe during these periods and is informed by an extensive review of the relevant literature. A combination of historical narrative, thematic, and content analysis was used in analysing the various documents into meaningful information addressing the objective of the study. Traditional societies in precolonial Zimbabwe had access to abundant natural resources. However, access to these resources was not uncontrolled, but was limited by traditional beliefs, taboos, and customs enforced through community leadership structures. The advent of colonialism in the late 19th century dispossessed indigenous African communities of natural resources through command-type conservation legislation. At independence in 1980, the new majority government sought to redress the natural resource ownership imbalances created during colonialism, culminating in some significant measure of devolution in natural resource management to local communities in the late 1980s, though such devolution has been criticised for being incomplete. An accelerated land reform exercise since the year 2000 has adversely affected biodiversity conservation activities in the country, including the conservation-related livelihood benefits derived from protected areas. The review paper highlights the need for a more complete devolution of natural resource ownership and management down to the grassroots levels in the communal areas, if social and ecological sustainability is to be fully realised in these areas. On the other hand, the disruption of conservation activities in the country due to the ill-planned accelerated land reform exercise that has demarcated land for arable farming in some of the protected areas should be held in check as a matter of urgency.

This paper highlights the implementation of Forest Rights Act to conserving protected areas in the country; Forest Rights Act (2006) has been passed by the parliament of India with dual aims of protecting the right of forest dwellers and at the same time this Act tries to acquire the involvement of forest dwellers to protect forest/protected areas. The main objective of the paper is to determine the factors which influence motivation to spend efforts in terms of work hour for biodiversity conservation in Nameri National Park. A total of 78 numbers of households were interviewed from two forest villages (i.e. Torajan and Dharikati) and two encroached villages (i.e. Rihajuli and Chopaloga) located in the south buffer of Nameri National Park in Assam during March and June of 2021. Respondents in forests village are more willing to spend effort than that of encroacher’s village to conservation. Sex, age, literacy of the respondents and size of land holdings were found to be significantly related to spending time for biodiversity conservation programme. In this paper attempt has been made to emphasize the nature of motivation of the communities towards biodiversity conservation issues.

Cross taxa congruence was investigated between butterfly taxa and ecological community for fine spatial scale (10 × 10 km² UTM grids) in north-eastern part of Turkey. The study area was evaluated within the scope of systematic conservation planning, and analyses were performed for sets of priority protected areas composed using complementarity-based site selection software Marxan. Cross taxa congruence was subsequently examined both in species richness and ecologic complementarity. Accordingly, it has been observed that the cross-taxon congruence between butterfly taxa and ecological community was relatively better than the results of previous studies. Another remarkable finding is that ecological community was a more robust surrogate than butterfly taxa. Although the results are valuable for conservation studies, they highlight the fact that a simple surrogate-based site selection would be inadequate to represent overall biodiversity.  The weakness of congruence patterns among surrogates would also lead to gaps in biodiversity conservation. These findings therefore draw attention to the necessities of incorporating surrogates of distinct ecology or some other surrogates like environmental parameters into conservation planning. Otherwise, there may be mistakes regarding species representation and the vast majority of species may be misrepresented in protected areas and protected area plans. At this point, it should be emphasized that understating cross taxa congruence and/or relationships is a key component for efficient biodiversity conservation.

AbstractThe jaguar Panthera onca, a threatened species in Brazil, is losing suitable habitat as a result of agricultural expansion and other forms of land conversion, especially in the Cerrado biome. In the current context of habitat loss and fragmentation, a network of protected areas is paramount for the conservation of this species. We aimed to identify jaguar conservation units in the Cerrado, and propose a ranking of priority areas for the species in this region. We used the maximum entropy algorithm to model habitat suitability for the jaguar in the Cerrado, with nine uncorrelated environmental variables and 106 non-autocorrelated presence-only records. We prioritized regions, using Zonation, and ranked jaguar conservation units according to their area, proximity to strictly protected areas, jaguar presence, and potential for connectivity. Circa 30% of the Cerrado is suitable for the jaguar. The most important variables affecting jaguar distribution are mean rainfall and land cover, with a high probability of jaguar presence in forest and savannah. We selected 31 high-priority jaguar conservation units, covering c. 174,825 km2 (8.5%) of the Cerrado. We emphasize the need for new protected areas and the promotion of sustainable development, as only 0.4% of the Cerrado (8,345 km2) has high environmental suitability for jaguars and < 1% of the area covered by jaguar conservation units falls within protected areas. Most jaguar conservation units identified here are relevant for habitat connectivity in Brazil, given their proximity to other critical areas for jaguar conservation in the Caatinga and the Amazon.
