“…Berkes [12] defined LEK as: “the accumulated body of knowledge, practices, and beliefs concerning the evolving relationships between humans and their environment and how that information is culturally transmitted through generations.” Using this approach in ecological research can provide useful perspectives for managing biological invasions and invaded ecosystems [2, 13]. As such, the present study sought to analyze indigenous knowledge concerning the invasion by Acacia mangium of indigenous lands in Roraima, Brazil, and to determine how to contribute to mitigating the environmental damage caused by these trees.…”

“…Researchers examining the perceptions of human societies in relation to the impacts of invasive plants have approached the subject from different angles, with some finding that these plants can take on positive roles [2, 8], while others have focused on their negative impacts on local social dynamics [7]. Based on these studies, there appear to be various schools of thought that support the exploitation of invasive species that cause ecological and social-environmental impacts, and it must be recognized that some invasive species actually assume positive roles in the lives and subsistence activities of rural communities due to their utility and the opportunity of generating extra income and promoting cultural continuity [8].…”

IntroductionInvasive plants can impact biodiversity as well as the lives of native human populations. Natural ecosystems represent sources of natural resources essential for the subsistence and socio-cultural continuity of these social groups. Approximately 30,000 ha of Acacia mangium were planted for commercial purposes in savanna areas surrounding indigenous lands in Roraima State, Brazil, at the end of the 1990s. We examined the local ecological knowledge of indigenous Wapichana and Macuxi Amerindians, members of the Arawak and Carib linguistic families, respectively, concerning A. mangium Willdenow (Fabaceae) in a savanna ecosystem (“Lavrado”) to attempt to understand its propagation beyond the limits of the commercial plantations and contribute to mitigating its impacts on socio-ecological systems.MethodsThe present study was undertaken in the Moskow, São Domingos, and Malacacheta communities in the Moskow and Malacacheta Indigenous Lands (ILs) in the Serra da Lua region of Roraima State, in the northern Brazilian Amazon region. Interviews were conducted with a total of 94 indigenous individuals of both sexes, with ages between 18 and 76, and low levels of formal schooling, with an average time of permanence in the area of 21 years; some still spoke only their native languages. The interviews focused on their ecological knowledge of the invasive, non-native A. mangium and their uses of it.ResultsThe informants affirmed that A. mangium negatively impacted the local fauna and flora, making their subsistence more difficult and altering their daily routines. Among the problems cited were alterations of water quality (71.3%), negative impacts on crops (60.6%), negative impacts on the equilibrium of the local fauna (52.1%), increased farm labor requirements (41.5%), and restriction of access to indigenous lands (23.4%). There were no significant differences between the opinions of men and women, nor between community leaders and nonleaders. Most of the interviewees (89%) felt that A. mangium had no positive importance for the local economy and saw no future prospects of beneficial use.ConclusionsThe Wapichana and Macuxi informants felt that the invasion by A. mangium had caused negative effects on the natural environment and on community subsistence in the indigenous lands due to its rapid and unwanted propagation. The similarity between the opinions of men and women and between community leaders and nonleaders demonstrates the existence of knowledge that is well distributed among these communities and transmitted within their communities through social–cultural interactions.

“…Social-ecological systems approaches offer a new, crossdisciplinary method for understanding dynamics of non-native species introductions (Roy et al, 2010;Sundaram et al, 2012). In our case study, we were able to illuminate relationships between Table 5 Multiple regression examining the relationship between the squareÀroot number of frogs per plot at each property and four environmental variables: mean% grass, mean% canopy cover, flying invertebrates abundance, and leaf litter invertebrates abundance (N = 87).…”

a b s t r a c tNon-native species introductions have the ability to affect both ecological and social systems, thus to address those outcomes both ecological and social influences on an invasion need to be understood. We use a social-ecological systems approach to investigate connections between human and ecological factors that affect efforts to control the non-native coqui frog (Eleutherodactylus coqui) on the island of Hawaii. The coqui frog is recognized as a 'pest' and 'injurious wildlife' by the Hawaii Department of Agriculture. Because the coqui occurs on many small private properties across the island, it is necessary to enlist private citizens in control efforts. Control efforts can include direct chemical control of the coqui as well as landscape manipulations that reduce habitat quality for the frog. On 85 private properties in 12 communities across the island, we measured the relationship between coqui abundance, residents' attitudes toward the coqui, their reported participation in control activities, and environmental variables that affect habitat quality for the frog. Residents' attitudes correlated with coqui frog abundance, but in an unexpected direction: People with more frogs on their property and those who owned that property tended to have less negative attitudes toward the coqui. In addition, negative attitudes toward the coqui were not significantly related to participation in control activities. Coqui abundance was related to a habitat variable, canopy cover, which can be manipulated by residents to reduce habitat quality and discourage coqui occupancy. Tolerance for this non-native species is likely to hinder attempts to engage residents in control efforts as the species' range on the island continues to expand. If this pattern of habituation is manifested with other non-native species considered to have potentially negative effects on the ecological or social environment, it would be important to recognize as early as possible because managers may be most effective at engaging citizens in control efforts before habituation becomes widespread.

Home gardens in villages near conservation areas play an important role, both in ecological and socio-economical aspects. The aim of this research was to identify plant species diversity in home gardens in Pancasila Village, Tambora Geopark in the Sumbawa Islands. Floristic surveys were conducted at 25 home gardens in the local community. In-depth interviews with informants were conducted to generate information related to species value and home garden management. Results of the study show that 87plant species (46 families) were grown in home gardens. These plants consisted of 49.56% Phanerophytes, 8.90% Chamaephytes, 25.28% Hemicryptophytes and 6.70% Cryptophytes. According to phytogeograpical origins, 24.41% of the species were exclusively Asian-Tropical species. These plants had numerous purposes, including staple food, spices and vegetables, fruit trees, shading trees and ornamental plants. Among all species in home gardens, some plants had high frequency percentages, including Nephelium lappaceum (52%), Bougainvillea spectabilis (40%), Mangifera indica (36%), Musa paradisiaca (36%) and Coffea sp. (32%). Most of the species were identified as exotic plant species and, therefore, attention to such species groups is needed to protect the environment and biodiversity of Tambora Geopark. Home gardens in Pancasila are ideal sites for biodiversity conservation. It is also crucial environmental component in rural tourism development.
