Some researchers have emphasised the importance of life history theory to welfare biology, as they argue certain traits of life history may predispose certain individuals to worse welfare outcomes and that this has a strong relationship with habitat fragmentation sensitivity.[8] It has also been suggested that while welfare biology, as a field in its infancy, lacks sufficient empirical studies on the welfare of wild animals, it can make up for this through the use of existing demographic data, currently used to inform biodiversity conservation, to inform future research efforts.[9] The application of welfare biology to rewilding projects has additionally been a subject of investigation, with "collaboration between local people, conservationists, authorities and policymakers" suggested as a means of establishing welfare biology as a discipline.[10]
