Abstract The emerald ash borer (EAB) has killed species (Fraxinus L.) in much of eastern North America, but it yet to reach the vast wetlands northern Minnesota, USA. In these wetlands, a single species, black nigra Marsh.) comprises majority trees and foundational role controlling ecosystem function. Given likelihood wide-spread mortality from EAB severe impacts, we examined potential for co-occurring tree replace ash, either through gap filling overstory or release understory. We addressed this objective by examining woody plant communities 32 mature sites located across large geographic region inclusive two distinct wetland types as defined hydrologic regime. Our results indicate region-wide lack capable replacing both types; thus there is very low existing replacement expansion These point an urgent need silvicultural intervention identify establish future-adapted non-ash so promote resilience face maintaining aspects functions.

Abstract As global agricultural systems face increasing challenges from pest pressures and environmental degradation, a paradigm shift towards more sustainable resilient practices is imperative. The field of biosecurity, encompassing strategic integrated approaches to managing risks human, other animal, plant life, has gained prominence as globalization facilitates the movement spread invasive species. This paper presents comprehensive biosecurity framework that seamlessly integrates management (IPM) strategies with sustainability principles enhance effectiveness control strategies. By combining proactive preventive measures, practices, IPM methodologies, we can create holistic approach safeguarding ecosystems, agriculture, public health. review outlines key components framework, benefits, challenges, practical applications incorporating into measures.

Based these characteristics, disturbances are placed into one three broad categories, gap-scale, intermediate-severity, or catastrophic disturbance, along gradient.

Abstract Black ash wetlands cover approximately 1.2 million ha of wetland forest in the western Great Lakes region, providing critical habitat for wildlife. The future these is critically threatened by a variety factors, including emerald borer ( Agrilus planipennis ; [EAB]), which has been eliminating native populations otherwise healthy throughout region since it was discovered 2002. To quantify potential impacts tree mortality from EAB on wildlife communities, we measured seasonal bird, mammal, and amphibian diversity black using dual approach: (1) documenting bird species across 27 mature reference northern Minnesota, USA (2) assessing how communities respond to experimental manipulations forests that emulate management strategies related impact EAB. In total, 85 were recorded entire study 57 species, 5 23 mammal species. Results sites show hydrologic regime, percentage canopy cover, understory important characteristics communities. there may be short‐term increases richness associated with changes structure due mortality; however, anticipated resulting EAB‐caused mortality, particularly conversion non‐forested wetlands, will lead significant shifts community composition.

One mitigation strategy being considered is planting of alternative tree species increase compositional diversity, however, there limited understanding how replacement tolerate flooding. A greenhouse experiment was used explore early survival and growth eighteen response five flooding durations (3, 6, 9, 12, or 15 weeks). Seedlings were assigned flood tolerance groups according their responses various duration treatments. Taxodium distichum (L.) Rich., Ulmus americana L., Betula L. able survive grow with up weeks. Thuja occidentalis Acer rubrum Larix laricina (Du Roi) K. Koch, Quercus bicolor Willd., alleghaniensis Britton had rates 6 weeks length.
