<para>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.</para> </section> </abstract> <keywordSet> <keyword>biomass</keyword> <keyword>browsing</keyword> <keyword>deer</keyword> <keyword>moose</keyword> <keyword>regeneration</keyword> <keyword>roots</keyword> <keyword>soil carbon</keyword> <keyword>soil respiration</keyword> <keywordThesaurus>LTER controlled vocabulary</keywordThesaurus> </keywordSet> <keywordSet> <keyword>organic matter</keyword> <keyword>disturbance</keyword> <keywordThesaurus>LTER core area</keywordThesaurus> </keywordSet> <keywordSet> <keyword>Harvard Forest</keyword> <keyword>HFR</keyword> <keyword>LTER</keyword> <keyword>USA</keyword> <keywordThesaurus>HFR default</keywordThesaurus> </keywordSet> <intellectualRights> <section> <para>This dataset is released to the public under Creative Commons CC0 1.0 (No Rights Reserved).

The plots were located in areas where they would not disturb ongoing research. Each plot used the 2 m × 5 m “Conant” design (Figure 1 in Conant et al. 2003 [Conant, R.T., Smith, G.R., Paustian, K. 2003. Spatial Variability of Soil Carbon in Forested and Cultivated Sites: Implications for Change Detection. J. Environ. Qual. 32:278–286.]) with six subplots. In each subplot, we collected a 10 cm × 10 cm organic horizon sample and then sampled the underlying mineral soil to a depth of 30 cm in 10 cm increments. The soil core was 4.7cm diameter.</para> </section> <section> <title>Soil carbon and root biomass Samples were brought to Boston University and kept refrigerated at 4°C until being processed. Samples were homogenized by sieving through 2-mm mesh and removing rocks and woody debris. At the same time, roots were picked and set aside. Subsamples of the sieved soils were dried at 60°C for at least 48 hours to determine soil gravimetric water content. The dry soil was later ground to a fine powder and burned in an elemental analyzer (model NC2500, CE Elantech) to determine carbon and nitrogen content. Roots were washed with deionized water and sorted into dead and live root pools according to their diameter (fine: less than 2mm, medium: 2–10mm, coarse: more than 10mm). Roots were then dried at 60°C until weight was stable (at least 48 hours). Dry root biomass was recorded. For some samples, live and dead roots were not separated, so no biomass is reported in the “live” and “dead” categories but the total biomass is reported in the “live+dead” category. In theory, all mineral soil samples should be 10cm thick (0–10cm, 10–20cm, 20–30cm). In practice, some samples are smaller than that or altogether missing, generally because we hit a large rock during sampling. The actual thickness of each sample is listed in the column labelled “thickness”.
