Wildlife Biologists Debate Acres To Square Km Yields For 2026 Reserves Canadian Roles And Duties
Big ideas make room for smaller actions having worked to conserve wildlife in this region for over 20 years, i have seen firsthand that by setting a sweeping goal of connecting 3.2 million acres (5,000 square miles, or 13,000 square kilometers), american prairie has reframed the scale at which conservation success is measured in the great plains. What might that mean for the creatures living there? Here the authors quantify the impact of recent cropland expansion on the habitat of representative pollinator, bird, plant species across the conterminous united states, showing diminished crop.

Is a big patch of protected land better than many small patches
Landscape experts have been entrenched in this debate for decades Now some of them are joining forces to find an answer. The debate whether single large or several small (sloss) patches benefit biodiversity has existed for decades, but recent literature provides increasing evidence for the importance of small habitats Possible beneficial mechanisms include reduced presence of predators and competitors in small habitat areas or specific functions such as stepping stones for dispersal
