Jelenlev

Jelenlev is a term used in environmental planning and wildlife management to describe a framework for integrating deer ecology into human-dominated landscapes. It emphasizes coexistence and non-lethal approaches to reduce conflicts between deer populations and human activities while preserving natural movement patterns.

Originating in planning discussions in northern Europe during the 2010s, the term lacks a single official definition. It is generally used to describe policies, designs, and monitoring programs that treat deer as a component of the ecosystem rather than a nuisance to be excluded.

Core elements include habitat connectivity and landscape permeability, deer-friendly land-use planning, traffic calming and crossings, advisory fencing, seasonal harvest considerations, community engagement, and data-driven monitoring of deer movements, populations, and damage; and reliance on non-lethal deterrence and adaptive management.

Applications are most common near towns, farms, and peri-urban areas where deer-vehicle collisions or browse pressure are problems. Assessments focus on reducing incidents, sustaining biodiversity, and aligning agricultural and conservation goals, though results depend on density, terrain, and governance capacity.

Critiques highlight the costs of infrastructure and monitoring, maintenance needs, potential unintended effects such as altered dispersal, and the complexity of coordinating multiple stakeholders with differing priorities.

Related concepts include wildlife corridors, urban ecology, non-lethal wildlife management, and ecosystem-based planning.
