Deer and Moose Browsing in Hemlock Removal Experiment at Harvard Forest 2008
Hemlock decline in New England is caused by direct and indirect effects of invasion of the hemlock woolly adelgid. Direct damage from the insect is causing gradual mortality of hemlock, and widespread harvesting of hemlock in advance of mortality, in contrast, causes immediate mortality and removal of biomass from the site. Although both processes affect thousands of acres of forest annually we have only a limited understanding of their effects on forest ecosystem function and productivity and the nature of the subsequent forest community. We anticipate that harvesting will yield different consequences than gradual mortality from the insect. Therefore we designed an experiment to simulate these contrasting impacts, by logging or girdling hemlock stands. Results from the experimental treatments will be compared to the changes observed in forests that are being infested by the adelgid, and can also be included in integrated analyses of a suite of large experiments that form a core component of the Harvard Forest LTER program. Deer and moose foraging can play a key role in shaping forest regeneration after disturbance in temperate forest. In 2008, we initiated a browsing survey of woody stems in the Simes hemlock removal experiment plots. There are regular moose sightings in the study area, and moose pellets are commonly found within the plots. Also, extensive browsing of tree regeneration in the logged plots was noted starting in 2007. Sampling of the 8 study plots was completed in Summer 2008. The next sampling is tentatively scheduled for Summer 2013.
Impacts of Deer and Moose on Soil Carbon, Soil Respiration, and Root Biomass at Harvard Forest since 2017
Over the past decade, several deer and moose exclosures have been built at Harvard Forest to study the effect of ungulate browsing on tree regeneration, species diversity, and composition. We built on the existing infrastructure to study the impacts of deer and moose browsing on soil carbon stocks (soil C, root biomass) in regenerating forests.
Role of Moose and Deer Browsing in Harvested Forests of Southern New England since 2008
In the past 20 years, moose have spread south from Vermont and New Hampshire and recolonized their pre-historical range limit in southern New England from which they had been extirpated almost 200 years earlier. Intensive moose browsing in the boreal forest has caused declines in forest density and shifts in species composition in some areas, generating considerable interest and concern among foresters, wildlife managers, and ecologists as to how moose along with white-tailed deer will impact forest development in this region. Harvard Forest in collaboration with researchers at the USGS Massachusetts Cooperative Research Unit has initiated a long-term study of the role of moose and deer in SNE forests using experimental exclosures. The design is a randomized block with 3 factors -- full exclosure, partial exclosure, and control plot. Full exclosures exclude both moose and deer but allow access to small mammals such as mice, squirrels, and rabbits. Partial exclosures have a 60cm opening around the bottom perimeter of the fence, which excludes moose but allows access to deer and other small and medium-sized animals. The design enables us to quantify forest composition and structure in areas (1) exposed to moose and deer browsing,(2) protected from moose and deer browsing, and (3) exposed to deer browsing but protected from moose browsing.

Monitoring juvenile Chinook salmon outmigration using rotary screw traps on Deer and Mill creeks
The California Department of Fish and Wildlife (CDFW) conducts juvenile salmonid emigration monitoring on Mill and Deer Creek (Tehama County, CA) annually from October through June using rotary screw traps (RSTs). Data from this monitoring is used to estimate juvenile spring-run Chinook salmon (Oncorhynchus tshawytscha) (spring-run) abundance and passage, identify yearling outmigration timing and alert resource agencies of juvenile spring-run presence in the lower Sacramento-San Joaquin Delta. This data will be included in the development of a juvenile production estimate (JPE) for spring-run Chinook salmon in the Sacramento River as required by Condition of Approval 7.5.2 of Incidental Take Permit No. 2081-2019-006-00 (ITP) issued by CDFW to California Department of Water Resources (DWR) for the long-term operation of the State Water Project. Salmonid data collected from the Mill and Deer RSTs, among other datasets, is also used by the Salmon Monitoring Team (SaMT) to understand the movement of juvenile salmon in the Sacramento River Watershed to estimate the number of winter-run and spring-run Chinook salmon that have entered the Sacramento-San Joaquin Delta (Delta). SaMT is a real-time operations monitoring team required by Condition of Approval 8.1.2 of the ITP which meets weekly from October through June, to provide advice for real-time management of SWP operations to DWR, CDFW, and the Water Operation Management Team (WOMT) to minimize take of winter-run and spring-run Chinook salmon in the Delta.

Weight, sex, age, beam diameter, antler points and teat length for harvested deer from 1984-2025 in Black Rock Forest, Cornwall, NY.
Data from white-tailed deer harvested within Black Rock Forest, Cornwall, New York are collected annually. Trained staff measure mass, antler beam diameter, and teat length (since 2010), estimate age via dentition, count antler points, and assess sex on all field-dressed deer. Heart girth, measured as chest circumference, was recorded from 1984 to 1998.
Monitoring adult spring-run Chinook salmon throughout the adult lifespan on Deer and Mill Creek
The California Department of Fish and Wildlife (CDFW) collects data on adult salmonids on Deer Creek and Mill Creek. Data is collected annually via redd surveys on Mill Creek and holding surveys on Deer Creek; video camera systems on both creeks collect data on upstream passage 24 hours a day, 7 days a week from February to August. Data from this monitoring is used to estimate adult escapement (upstream passage) abundance and timing, spawner abundance, and other important metrics for adult salmonids in the watershed. These data will also be used to inform the development of a juvenile production estimate (JPE) for spring-run Chinook salmon in the Sacramento River Watershed as required by Condition of Approval 7.5.2 of Incidental Take Permit No. 2081-2019-006-00 (ITP) issued by CDFW to California Department of Water Resources (DWR) for the long-term operation of the State Water Project.

Counts of White-Tailed Deer Florivory: Long-Term Nitrogen Deposition: Population, Community, and Ecosystem Consequence
These data were collected in the e001 experiment within Field C to better characterize the impact of white-tailed deer on the plant community. These data represent counts of plant stems with an inflorescence present or those with evidence of herbivory that was interpreted as deer florivory.
Data from: Deer-mediated ecosystem service vs. disservice depends on forest management intensity
MANUSCRIPT ABSTRACT <p>As global terrestrial biodiversity declines via land-use intensification, society has placed increasing value on non-commercial species as providers of ecosystem services. Yet, many deer species and non-crop plants are perceived negatively when they decrease crop productivity, leading to reduced economic gains and human-wildlife conflict. We hypothesized that deer provide an ecosystem service in forest plantations by controlling competition and promoting crop-tree growth, although the effects of herbivory may depend on forest management intensity. If management negatively affects foraging habitat at local and landscape scales, then we expected browsing to shift to less-palatable crop trees. To test these hypotheses, we established a 5-year experiment that manipulated early forest management intensity via herbicide treatments and access of two deer species to vegetation via exclosures. Contrary to our hypothesis, deer provided an ecosystem service at high management intensities and a disservice occurred with low-intensity management. Crop-tree growth and survival was greatest when herbivory and herbicides suppressed broadleaf regeneration. In contrast, crop-tree growth was lowest when broadleaf vegetation was retained and crop-trees were subject to both browse damage and competition. We found a positive, yet variable, association between deer detections and stand- and landscape-scale broadleaf habitat, and despite initial reductions in forage, herbivory pressure was similar among management intensities. When broadleaf vegetation was suppressed by herbicides and herbivory, selection of herbaceous forage by deer intensified, likely aiding in the service. Overall, our findings indicate that the effects of vegetation management for promoting timber production are highly dependent on the presence of large herbivores.</p> <p>Synthesis and applications: Although deer are thought to reduce crop productivity in many systems, we found that herbivory switched from reducing crop tree growth where non-crop vegetation was retained, to promoting crop tree growth when both herbivory and herbicides suppressed competing vegetation. However, the provision of this ecosystem service is likely contingent on the amount of forage available in the landscape and subsequent foraging pressure. We conclude that nature's capacity to provide ecosystem services depends on the intensity of management at local and landscape scales.</p>
