OpinionDoes research help to safeguard protected areas?
Highlights
► Field research in protected areas generally appears to aid park conservation. ► Poachers and encroachers tend to avoid areas frequented by scientists. ► Much remains unknown about the generality of this ‘science-safeguarding effect’.

Are protected areas protected?
In a world beset by environmental challenges, protected areas are seen as a cornerstone of efforts to sustain the biodiversity and natural ecosystem processes of the Earth. The good news is that we have more protected areas than ever: since 1985, the total land area with at least some legal protection has more than tripled, now totaling 13% of the global terrestrial surface [1].
The bad news, however, is that many protected areas are under threat (Figure 1) 2, 3, 4, 5. Some areas are plagued by
Apparent advantages of researcher presence
If protected areas benefit from a science-safeguarding effect, an ancillary and sometimes hidden benefit of research may be promoting nature conservation. What is the evidence? In the most direct sense, several ‘conservation heroes’ have battled to establish or sustain protected areas (Table 1). Obvious examples include Dian Fossey in Rwanda [10], Daniel Janzen in Costa Rica, Patricia Wright in Madagascar, and Sir Ghillean Prance in Argentina [11]. Scientists employed by conservation
Limitations of science safeguarding
Despite such apparent successes, the science-safeguarding effect seems partial at best. In response to burgeoning Asian demands for ivory and rhino horn, Africa is the midst of an epic elephant [26] and black rhino [27] slaughter by armed poachers, rebels, and even the military that scientists and park managers have largely been unable to stop. At Los Amigos Biological Station in Peru, illegal gold miners threatened to burn down the research station when scientists tried to halt their
Concluding remarks
It is remarkable that the effects of field research on the conservation values of protected areas have yet to be assessed systematically. To what degree does research benefit or harm park values? Can research activity be optimized in space and time to maximize its benefits for conservation? Are heavily studied areas, such as the vicinities of popular research centers, biased biologically because their faunal communities have been altered by researcher activity? These are but a sampling of

2021, Biological ConservationCitation Excerpt :Protected areas are the most important tool for conserving biodiversity and ecosystem services (Bruner et al., 2001), but may be especially vulnerable to the effects of reducing public mobility such as occurred in response to COVID-19 pandemic. In addition to lower levels of enforcement due to restricted work practices of park employees, there may also be fewer visits by environmental NGO staff and researchers whose presence has a safeguarding effect (Piel et al., 2015; Laurance, 2013). Moreover, for PA designations such as National Parks that encourage public visitation, reductions in public mobility may affect park revenues and significantly reduce the multiple contributions (monetary and non-monetary) that parks make to societies (Jepson et al., 2017; King and Stewart, 1996).
Are protected areas effective in preserving anurans and promoting biodiversity discoveries in the Brazilian Cerrado?
2019, Journal for Nature ConservationCitation Excerpt :Thus, protected areas have also an important scientific role in reducing biodiversity knowledge shortfalls (Barata, Correia, & Ferreira, 2016). Indeed, the conservation and scientific roles mutually promote each other; while PAs favor researchers to improve biodiversity knowledge from pristine landscapes, the presence of field researchers benefit PAs by inhibiting improper users, such as poachers and encroachers (Laurance, 2013). In Brazil, the number and coverage of PAs have progressively grown over recent decades, but particularly restricted to the Amazon domain (Araújo, 2007; Cabral & Brito, 2013; Jenkins & Joppa, 2009).
