DBG Physaria bellii Demographic Monitoring

Последняя версия опубликована Kathryn Kalmbach Herbarium (Denver Botanic Gardens) Jun 4, 2018 Kathryn Kalmbach Herbarium (Denver Botanic Gardens)

This dataset consists of data collected when monitoring a population of the imperiled (G2) species Physaria bellii G. Mulligan. Observations and data were recorded once per year in 2017, 2008, 2009, 2011, 2013, and 2016. Observations were made within a 30 meter by 20 meter macro-plot, within which are smaller 30 meter by 1 meter sub-plots (may be referred to as transects). Data recorded consists of the location of plants within a sub-plot, the number of other P. bellii individuals (rosettes) within the immediate surrounding vicinity of the plant of interest, if the plant was flowering, the number of inflorescences present, the number of fruits present, and if any animal herbivory is exhibited on the plant of interest.

This dataset consists of data collected when monitoring a population of the imperilled (G2) species Physaria bellii G. Mulligan. Observations and data were recorded once per year in 2017, 2008, 2009, 2011, 2013, and 2016. Observations were made within a 30 meter by 20 meter macro-plot, within which are smaller 30 meter by 1 meter sub-plots (may be referred to as transects). Data recorded consists of the location of plants within a sub-plot, the number of other P. bellii individuals (rosettes) within the immediate surrounding vicinity of the plant of interest, if the plant was flowering, the number of inflorescences present, the number of fruits present, and if any animal herbivory is exhibited on the plant of interest. Physaria bellii G. Mulligan is a rare endemic species of the northern Front Range foothills of Colorado. Populations are known from Boulder, Jefferson, and Larimer Counties. The species is ranked imperiled globally and statewide (G2/S2). Primary threats to the species are mining, suburban expansion, and road construction, as well as invasion of habitat by noxious weeds. Due to threats and lack of data on the health of this species, Denver Botanic Gardens and the Colorado Natural Areas Program initiated the groundwork for a population trend study of P. bellii in 2007. One macroplot was installed and sampled in 2007 and resampled in subsequent years. This annual sampling provides an opportunity for volunteers to gain field experience as part of the Rare Plant Monitoring Steward program. The goal of the study is to document the population size of P. bellii at this site over time. Physaria bellii was first described by Gerald A. Mulligan in 1966 from seed propagated from a specimen near Boulder, CO (Mulligan 1966). Currently, populations are known from outcrops of the Niobrara and Pierre formations in the northern Front Range of Colorado. Physaria bellii is usually found in shrub communities dominated by Rhus trilobata and Cercocarpus montanus in the Niobrara and Pierre Formation shales and limestones, at elevations of 1580 to 1750 meters. There are 25 known occurrences of P. bellii with approximately one million individual plants (NatureServe 2008). Physaria bellii forms a basal rosette with broadly obovate leaves that are obtuse at their apex, and have a silvery pubescence with flat stellate hairs. Flowers are yellow, and bloom from March to May (see Figure 2). Fruit appear from June to July and form a silique of twin papery sacs with a constriction separating the locules that is equally deep above and below (Spackman et al., 1997).

Название DBG Physaria bellii Demographic Monitoring
Описание района исследования In 2007, Denver Botanic Gardens and Colorado Natural Areas Program set up a macro-plot to monitor Physaria bellii at Park Creek Hogback Natural Area (formerly called North Poudre Reservoir Natural Area) in Larimer County, Colorado. Park Creek Hogback Natural Area is northwest of Ft. Collins, along County Road 72, at an elevation of approximately 1525 meters. The area around the macro-plot is characterized by dry and loose gray shale slopes and sagebrush, including invasive species such as Linaria genistifolia spp. dalmatica (Dalmation toadflax).
Описание плана выполнения исследований The Physaria bellii transect is found along the western slope of the ridge. The 20m x 30m plot is located along the ridge, 43 meters north of the barbed wire fence. Each transect within the macroplot is 30 x 1 meters, and are placed at 2 meters intervals starting from 1.97 meters from the south west corner of the macroplot. On the south grid of the plot, a nail and its number are allotted. Run a tape measure 30m parallel with the ridge. Straighten tape (make sure tape measures 30m long). Some nails on the north edge are placed at more than 30m due to rocks or constraints of the soil but measurements should only be recorded to 30m. Position a 1m x 30m macro-plot in the correct location for the macro-plot to be sampled, i.e., meters 7.97-8.97 x 30m for plot 7.97m (tag #86). Before beginning actual observation, make sure you fill in the name of the site, plot # (meter), tag # (nail tag), page # per plot, date and your name. Count all Physaria bellii that fall within the plot or touch the south and west lines of the macro-plot (see Figure 1). Plants touching the north and east lines are considered out and not recorded. For X-coordinate (0-100cm) and Y-coordinate (0-30m), record the distance from the starting point to the center of the plant, i.e., 0.55m (55cm) and 22m. If you find a cluster of tiny Physaria bellii rosettes, record the distance to the center of the cluster for the X-coordinate and Y-coordinate, and then count the number of rosettes in the cluster. Record whether the plant is flowered (i.e., 0 or 1), and the number of flowering stems. If the plant has fruit, please count the number of fruit on the plant. Record whether the plant is browsed by insects or mammals, trampled by human or mammals (i.e., 0 or 1). In the comment section, describe the type of browsing observed and the condition of the plant, if any. Note: 0-absence, 1-presence.
