In this paper we focus on the pressing need to effectively engage with Indigenous Peoples and Local Communities (IPLCs) and the need to strengthen the capacity of rangers originating from these communities. Opportunities for full participation and leadership by IPLCs are improved by enhancing the role of Indigenous and local rangers in fostering relationships while integrating cultural knowledge into the work on the ground. This also strengthens local benefits. We emphasize the invaluable contribution of IPLCs to conservation, often honed over generations, and explore current models of partnership and engagement. Particularly, we spotlight the vital role of IPLC rangers, who leverage unique skills, local knowledge, and cultural practices in their conservation work. The roles of both IPLCs and local Indigenous rangers are essential if we are to meet our goals for conserving 30% of the earth’s lands and waters by 2030 as promoted at the COP15 meeting of the Convention on Biological Diversity (CBD), achieve the objectives for development of IPLC rangers as stated of Chitwan Declaration of 2019 (CD), or meet the related targets set by the Universal Ranger Support Alliance (URSA). We advocate for a partnership model with IPLCs that applies the principles of Collective Impact to improve outcomes and secure enduring benefits at all levels. To aid stakeholders in conservation projects involving IPLCs (including governments, businesses, and non-governmental organizations), we propose a straightforward summary framework that outlines stages for the development of relationships and projects. It integrates the work of others, including foundation principles, management systems for partnerships, and good practices, and stresses the need for pre-project training, learning and other forms of preparation. Altogether, these principles and accompanying recommendations help lay the groundwork for effective intergenerational projects involving IPLCs with long-term benefits.
