Species Lists Introduction

Introduction
The next six sections consist of species lists of all of the vascular plants, mammals, birds, reptiles, amphibians, and butterflies found at Wortroot during this inventory. Since common names have been used throughout the rest of this report, these lists can be used to find the scientific names of each species, as well as to find other information about their status at Wortroot.

All of the lists place species in phylogenetic order, so that closely related species are close together on the list. The order of species in these lists will match the order in many field guides and checklists. The only exception is that within plant families, species are placed in alphabetical order by scientific name.

Rare Species
Several species found on the property are on the Virginia Rare Plant or Animal Lists, both of which are lists of species which are rare or of uncertain status in Virginia. Other species are on the Virginia Watchlists, meaning that they are in need of monitoring in the state. The following abbreviations are used in the species lists to refer to these species' status globally and in Virginia.

G3 = Either very rare and local throughout its range or found locally (even abundantly at some of its locations) in a restricted range; or vulnerable to extinction because of other factors. Usually fewer than 100 occurrences are documented.
G4 = common and apparently secure globally, though it may be rare in parts of its range, especially at the periphery.
G5 = very common and demonstrably secure globally, though it may be rare in parts of its range, especially at the periphery
G_T_ = signifies the rank of a subspecies or variety. For example, a G5T4 would be a subspecies of a species that is demonstrably secure globally (G5) but the subspecies warrants a rank of T4, rare in parts of its range.
S1 = Extremely rare and imperiled with five or fewer occurrences or very few remaining individuals in Virginia; or because of some factor(s) making it especially vulnerable to extirpation in Virginia.
S2 = Very rare and imperilled with 6 to 20 occurrences or few remaining individuals in Virginia; or because of some factor(s) making it vulnerable to extirpation in Virginia.
S3 = Rare to uncommon in Virginia with between 20 and 100 occurrences; may have fewer occurrences if found to be common or abundant at some of these locations; may be somewhat vulnerable to extirpation in Virginia.
S4 = Common and apparently secure with more than 100 occurrences; may have fewer occurrences with numerous large populations.
S5 = Very common and demonstrably secure in Virginia, though it may be rare in parts of its range, especially at the periphery.
SZN = Long distance migrant whose occurrences outside of the breeding season are not monitored or a species whose wintering populations are transitory and usually do not occur regularly at specific localities.
SC = Special Concern; animals that merit special concern according to the Virginia Department of Game and Inland Fisheries. This is not a legal category.
LT = Listed threatened federally. A taxon is likely to become endangered in the foreseeable future.
B = This suffix refers to the breeding status of the animal.
N = This suffix refers to the nonbreeding status of the animal.
? = A ? following the status means that the plant's rank is uncertain.
