Southwestern white pine (Pinus strobiformis) is a species of ecological significance in the mixed-conifer forests of the Southwest and Mexico but is threatened by recent outbreaks of the disease white pine blister rust, which causes stem and branch cankers that decrease reproductive fitness in mature, seed-bearing trees.<\/p>\n<p>The lab has been collecting southwestern white pine cones and seeds since 2012 for gene conservation and within these collections we are continuing to inventory cone and seed insects associated with the southwestern white pine. During 2012 and 2013, we caged insect-damaged cones to rear insects, which we have been cataloging and identifying. Between May and August, 2014, we have been caging cones on individual trees as well as clipping and dissecting cones to identify insects and assess damage. Caged cones will be collected and dissected in early fall. We also plan to x-ray a subsample of seeds to quantify damage by the seed bug (Genus Leptoglossus). This marks the first attempt to fully document cone and seed insects associated with southwestern white pine and quantify their damage. Results of this project will be documented in a peer-reviewed publication as well as a photo guide for managers in the Southwest.<\/p>\n<p><strong>Funding:<\/strong>\u00a0USDA Forest Health Monitoring Evaluation Monitoring Program and USDA Genetic Conservation<\/p>\n<\/body><\/html>\n    <\/div>\n<\/div>\n\n<!-- shortcode-accordion -->\n<div class=\"shortcode-accordion shortcode-accordion--closed\" style=\"position: relative;\" >\n        <h4 class=\"shortcode-accordion__header\">\n        <button type=\"button\" class=\"shortcode-accordion__trigger\" data-header=\"Stand response to western spruce budworm (Choristoneura occidentalis) defoliation and mortality in New Mexico_0\" id=\"shortcode-accordion-4-trigger\" aria-expanded=\"false\" aria-controls=\"shortcode-accordion-4-panel\">\n            Stand response to western spruce budworm (Choristoneura occidentalis) defoliation and mortality in New Mexico\n            <span class=\"shortcode-accordion__header__arrow\" aria-hidden=\"true\"><\/span>\n        <\/button>\n    <\/h4>\n    <div class=\"shortcode-accordion__body\" id=\"shortcode-accordion-4-panel\" role=\"region\" aria-labelledby=\"shortcode-accordion-4-trigger\" inert>\n        <html><body>\n<p><strong>Investigators:<\/strong>\u00a0Adam Polinko, Connor Meehan, Eric Vane, Kristen Waring, Matt Blanford<\/p>\n<p><strong>Description:<\/strong>\u00a0Populations of western spruce budworm (Choristoneura occidentalis), a native defoliator of western conifers, have been at elevated levels in northern New Mexico for up to 20 years in some locations, causing extensive dieback and mortality of susceptible tree species (Douglas-fir, white fir, corkbark fir, and Engelmann spruce primarily). We are investigating how species composition and future stand structure and composition are being impacted by prolonged western spruce budworm defoliation in mixed conifer and spruce-fir forests.<\/p>\n<p>Preliminary results indicate high mortality of true fir in spruce-fir forests, coupled with dying and defoliated spruce, leaving few live trees. We are also investigating the relationship between western spruce budworm outbreaks, climate, and site characteristics in spruce-fir forests using multispectral satellite imagery and modeled climate data. Using these methods, we will analyze current insect outbreaks in a changing climate, and predict the future behavior of outbreaks if certain climactic scenarios persist.<\/p>\n<p><strong>Funding:<\/strong>\u00a0NAU School of Forestry Mission Research Program (McIntire-Stennis funds), NAU Intern-to-Scholars Program (C.

Regional land managers have expressed a desire for an empirically supported and management-oriented classification tool for pi\u00f1on-juniper vegetation types. We are utilizing a US Forest Service \u2013 Forest Inventory and Analysis (FIA) dataset of pi\u00f1on-juniper vegetation from the Southwest to i) elucidate the biotic, edaphic, disturbance, and climatic components related to pi\u00f1on-juniper community composition and abundance Southwest; ii) validate previous pi\u00f1on-juniper classification systems; and iii) develop a management-oriented identification tool for pi\u00f1on-juniper vegetation types.
