ABSTRACT:
This data set consists of two tables. The first table contains life demography stages for two round-leaved orchid taxa, Platanthera macrophylla and P. orbiculata, over the years 2011-2015. The second tables contains leaf area measures by orchid and life stage. Data have been published in: Cleavitt, NL.; Berry, EJ, Hautaniemi, J, and Fahey, TJ. 2017. Life stages, demographic rates, and leaf damage for the round-leaved orchids, Platanthera orbiculata (Pursh.) Lindley and P. macrophylla (Goldie) PM Brown in a northern hardwood forest in New Hampshire, USA. Botany 95 (1): 61-71.

Field Sampling
Beginning in the summer of 2011, all individuals of the round-leaved orchids sighted in the HBEF were marked and mapped. Individuals were marked with a bright pink PVC flag and given a unique number. The location of groups of orchids were recorded in a GPS data base gathered using handheld Garmin GPS. Individual orchids were additionally mapped relative to each other within groups by compass and metre tape. Orchids were visited three times a season from 2011 to 2015 for flowering individuals (early spring, July for flower data, late August – early Sept for capsule data) and at least once a season for nonflowering individuals to record life stage and leaf data.
