This resource update contains the findings of a survey conducted on a sample of all primary wood-using mills in Massachusetts. It complements the Forest Inventory and Analysis (FIA) annual inventory of volume and removals. The survey was conducted to determine the amount and source of wood receipts and annual timber product imports/exports. Only primary wood-using mills were surveyed. Primary mills are those that process roundwood in log or bolt form or as chipped roundwood. Examples of industrial roundwood products are saw logs, pulpwood, veneer logs, poles, and logs used for composite...

Community-based conservation (CBC) emerged in the 1980s as part of a paradigm shift from unpeopled protected areas to people-centered efforts to connect conservation and development. Although well intentioned, the change prompted a focus on communities as either passive subjects or secondary participants of mostly top-down, externally-initiated interventions - many which framed people as separate from nature and, therefore, as a threat to it. As conservationists embrace a new paradigm first characterized by geologists as the "Anthropocene," conservation priorities and successes increasingly...

Density management diagrams (DMDs) are a fundamental forest management tool. However, these tools were primarily developed for even-aged stands and may not incorporate important site effects. Accommodating different stocking constraints during stand development across broad ranges of site effects could help tailor reforestation and thinning prescriptions to local conditions. For that purpose, this report introduces a set of site-sensitive DMDs for managing both even- and uneven-aged California mixed-conifer stands. By consulting maps of aridity and nitrogen deposition summarized by...

In the national forest inventory of the USA, there is an ongoing issue with sample plots that are either completely or partially unmeasured due to access issues such as hazardous conditions or lack of permission. The nonrandom nature of the nonresponse in the general population potentially creates a bias in the sample and resulting estimations. A potential mitigation option is the use of response homogeneity groups in combination with ratio-to-size estimators. This paper presents an extension of this approach where per-unit area estimates commonly useful to practitioners, e.g. number of...

We used national forest inventory data from Michigan, Minnesota, and Wisconsin, U.S.A. to produce estimates of the annual areal extent of wind disturbance for 2005–2018. Our results indicate that at least for wind in the region, including the panel of plots assigned to the inventory year coincident with the disturbance year produces estimates that are lower than estimates computed with that specific inventory year excluded. We attributed this result to partial observation of disturbance for that year, a situation that arises from the operational necessity of a year or more being required...
