“…Green turtles in the Torres Strait are known to be part of the northern Great Barrier Reef stock (Limpus 2008). Dugong also migrate widely in Australian tropical waters, possibly driven by changes in seagrass abundance (Marsh et al 2002, Sheppard et al 2006. Their migratory behavior has necessitated cross-scale partnerships between multiple indigenous communities, state and national government agencies (Kennett et al 2004, Wohling 2009, and cross-border collaboration between Australian and PNG stakeholders in the Torres Strait (DEC 2009).…”

ABSTRACT. In many developing regions of Melanesia, fishers' traditional ecological knowledge (TEK) has been integrated with western science and management knowledge (SMK) to generate innovative and effective fisheries management. Previous research suggests that three factors initiate this process: depleted fishery stocks, limited SMK, and ownership of resources by local communities. In other contexts the extent of power-sharing through comanagement, and the cultural significance of species may also be important determinants of knowledge integration. Here we assess the role of these factors in the application of TEK in the Torres Strait Islands, Australia, where commercial and subsistence fisheries are fundamental to the Indigenous Melanesian culture and livelihoods. In 2009 we surveyed fishery managers and scientists who revealed that TEK had only been recently and sparingly applied in four fisheries (turtle, dugong, lobster, and hand collectables), and only two of the seven species concerned had a combination of depleted stocks, low SMK, and high community ownership. Instead, comanagement characteristics and the cultural value of species were the primary determinants of TEK application. We suggest that turtles and dugong are cultural keystone species that simultaneously provide important ecosystem services to both islanders' livelihoods and international conservation interests. Combined with their ecological scale these species have catalyzed comanagement between indigenous and government stakeholders, precipitating the application of TEK in other fisheries of lesser cultural importance. We discuss modifications to governance required to enable knowledge integration to evolve further through adaptive comanagement, and its role in enhancing fisheries management and thus the resilience of the Torres Strait social-ecological system. Our study highlights the potential utility of cultural keystone species in stimulating cross-cultural resource governance in developed economies such as Australia.

“…In recent years, the value of traditional environmental knowledge has been recognized as a valuable source of ecological information. In the case of the Amazonian manatee, it includes not only a vast reservoir of information regarding the behavior and ecology of the species, but maybe the existence of effective indigenous strategies for ensuring Seasonal migrations have been well documented in other Sirenians: the Florida manatee Trichechus manatus latirostris (Deutsch et al 2003) and the dugong Dugong dugon (Sheppard et al 2006); and suggested in Antillean manatees T. m. manatus (Self-Sullivan et al 2003, CastelblancoMartínez et al 2013. The ecological processes that drive migration often seem to be related to habitat variability.…”

What do Local People Know About Amazonian Manatees? Traditional Ecological Knowledge of Trichechus inunguis in the Oil Province of Urucu, AM, Brazil

During 2005-2007, a series of interviews were carried out with the riverside populations of the Oil Province of Urucu (AM, Brasil). The main goal of this work was to characterize the knowledge of the inhabitants of this area regarding the Amazonian manatee (Trichechus inunguis) (listed as Vulnerable on the IUCN Red List). Interviews were conducted with 74 local inhabitants from 33 communities. Between 2004 and 2007, 20 poached or entangled Amazonian manatees were reported in the area. Poaching with harpoon is the principal cause of mortality, but manatees are also incidentally caught in fishing nets. Interviewers described details of manatee hunting techniques in the area. The trade of manatee meat, although currently forbidden by Brazilian laws, still occurs in the area. Data obtained from the interviews suggest a dietary preference of the manatee for at least 29 species of aquatic and semi-aquatic plants. The interviewed fishermen showed a sound knowledge of Amazonian manatee biology and behavior. This information may be important to assist future conservation plans in the Amazon.

“…For example, in the Coral Sea, off the northeast coast of Australia, nesting green sea turtles (Chelonia mydas) tagged in Australia migrate to international feeding grounds in New Caledonia and back to their nesting grounds in Australia, crossing state, national, and international boundaries as they migrate (Read et al, 2014). Within Australia, some dugongs cross state jurisdictions when they make seasonal migrations between Queensland and New South Wales (Allen et al, 2004;Sheppard et al, 2006). The disconnect between governance levels complicates the management of migratory species, as state and national legislation and management can conflict (Ruckelshaus et al, 2008;Read et al, 2014) and fail to take account of the cumulative impacts on migrating animals.…”

Protecting Migratory Species in the Australian Marine Environment: A Cross-Jurisdictional Analysis of Policy and Management Plans

Marine migratory species are difficult to manage because animal movements can span large areas and are unconstrained by jurisdictional boundaries. We reviewed policy and management plans associated with four case studies protected under the Australian Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999) in order to identify the coherence of policy and management plans for managing marine migratory species in Australia. Environmental policies (n = 23) and management plans (n = 115) relevant to marine turtles, dugongs, humpback whales, and migratory shorebirds were reviewed. Few of the reviewed policies (n = 7) listed protected species and even fewer (n = 4) listed protected marine migratory species. Marine turtles were most represented in the reviewed policies (n = 7), while migratory shorebirds were most represented in management plans (n = 59). Policies and management plans were much more likely to identify relationships to other policies or plans within the same jurisdiction than to different jurisdictions. The EPBC Act 1999 served as the central link between reviewed policies and plans, but the requirements of that Act were weakly integrated into the other documents. This weak integration and the biases toward specific migratory species in environmental policies and management plans are detrimental to the conservation of these Matters of National Environmental Significance in Australia. Any changes to the EPBC Act 1999 will affect all environmental policy and management plans in Australia and highlights a need for cooperative, multi-level governance of migratory species. Our findings may have relevance to the conservation of marine migratory species in a broader international context.
