PROPOSED RULEMAKING

DEPARTMENT OF CONSERVATION AND NATURAL RESOURCES

[ 17 PA. CODE CH. 45 ]

Conservation of Pennsylvania Native Wild Plants

[47 Pa.B. 7210]
[Saturday, November 25, 2017]

 The Department of Conservation and Natural Resources (Department) proposes to amend Chapter 45 (relating to conservation of Pennsylvania native wild plants) to read as set forth in Annex A.

A. Effective Date

 This proposed rulemaking will go into effect upon final-form publication in the Pennsylvania Bulletin.

B. Contact Persons

 The primary contact for questions regarding this proposed rulemaking is Rebecca H. Bowen, Chief, Ecological Services, Bureau of Forestry, Department of Conservation and Natural Resources, P.O. Box 8552, Harrisburg, PA 17105-8552, (717) 787-3444, rebbowen@pa.gov. The secondary contact for questions regarding this proposed rulemaking is Stephen Ekema-Agbaw, Assistant Counsel, Office of Chief Counsel, Department of Conservation and Natural Resources, P.O. Box 8767, Harrisburg, PA 17105, (717) 772-4171, sekema@pa.gov.

C. Statutory Authority

 This rulemaking is proposed under section 7 of the Wild Resource Conservation Act (WRCA) (32 P.S. § 5307) and sections 305(a)(9) and 313(g) of the Conservation and Natural Resources Act (CRNA) (71 P.S. §§ 1340.305(a)(9) and 1340.313(g)).

 Section 7(a) of the WRCA provides that ''the [former] Department of Environmental Resources shall. . .conduct investigations on wild plants in order to ascertain information relating to. . .other biological and ecological data to classify plants and to determine management measures necessary for their continued ability to sustain themselves successfully.'' Under section 7(c) of the WRCA, ''[o]n the basis of such determinations, the Environmental Quality Board shall issue regulations not later than two years from the effective date of'' the WRCA. Under section 7(c) of the WRCA, ''[t]he Environmental Quality Board may add or delete species as conditions change and may modify regulations to reflect the changing environment.''

 Section 305(a)(9) of the CRNA transferred to the Department ''the powers and duties vested in the Department of Environmental Resources by the. . .Wild Resource Conservation Act.'' The former Department of Environmental Resources was the Department's predecessor in this interest. Section 313(g) of the CRNA transferred to the Department ''the powers and duties previously vested the Environmental Quality Board by. . .[s]ections 7, 8 and 9'' of the WRCA.

D. Purpose and Background

Purpose

 This rulemaking proposes to amend Chapter 45 by updating: 1) the classification lists of native wild plants; 2) the scientific and common names of certain native wild plants; and 3) the reference source that the Department uses for the names of native wild plants.

 Regarding updates to the classification lists of native wild plants, this rulemaking proposes to amend the following classification lists: Pennsylvania Extirpated (§ 45.11); Pennsylvania Endangered (§ 45.12); Pennsylvania Threatened (§ 45.13); Pennsylvania Rare (§ 45.14); and Tentatively Undetermined (§ 45.21).

 This rulemaking proposes to amend the classification lists by: 1) adding plants that are currently unclassified to a classification list; 2) reclassifying plants already on a classification list to a new classification; and 3) removing plants from the classification lists altogether (declassifying them).

Process of classifying native wild plants in Pennsylvania

 Native wild plant species are those plant species that existed in this Commonwealth prior to European settlement. There are approximately 2,800 native wild plant species that currently exist or formerly existed in this Commonwealth. The Department classifies approximately 1/5 of these species because they are a conservation concern; the other 4/5 are considered secure and thus not classified.

 The Department begins the process of classifying native wild plants by collecting and analyzing data on native wild plant species in this Commonwealth. The Department uses the following data to make its classification decisions: numbers of populations known in this Commonwealth; number of individuals within populations; the plant's range (amount of ground that it covers); threats such as pests, invasive species and habitat loss; decrease or increase in population numbers; and taxonomic information. The previous list is not exhaustive. The Department analyzes this data to determine the population, distribution, habitat needs, limiting factors, and other biological and ecological information about each plant species.

 An important piece of data that the Department uses to make classification decisions are referred to as ''State ranks.'' In this Commonwealth, each plant species receives a State rank from the Pennsylvania Natural Heritage Program (PNHP). The PNHP assigns these ranks based on a methodology created by Nature Serve, an international network of natural heritage programs. The purpose of Nature Serve's methodology is to bring consistency to the biodiversity conservation efforts of individuals and organizations throughout the Western Hemisphere. This methodology is used across North America, Central America and South America. By using this standard tool, the Department ensures its evaluation methods are, at a minimum, equivalent to that of other states and countries in the Western Hemisphere and that its classification decisions are based on sound science.

 Throughout this process the Department also receives data, information and recommendations from the Pennsylvania Biological Survey's Vascular Plant Technical Committee (Committee). The Committee is composed of professional botanists working throughout this Commonwealth in academic, consulting, governmental and conservation organizations. Each year, the Committee makes classification recommendations for native wild plants based on the research and expertise of its professional botanists.

 The Department assimilates and reviews all data and recommendations it collects and receives, and determines the appropriate classifications for each native wild plant species under the definitions in Chapter 45.

Native wild plant classifications

 Under section 7(a) of the WRCA, how plants are classified determines the ''management measures necessary for their continued ability to sustain themselves successfully.'' Native wild plant species that are at risk of extinction in this Commonwealth need greater protection than those less susceptible to this risk. Chapter 45 designates the level of risk facing native wild plant species in this Commonwealth by classifying them as follows:

Pennsylvania Extirpated (§ 45.11)—A classification of plant species believed to be extinct in this Commonwealth. If a plant species classified as Pennsylvania Extirpated is later found to exist in this Commonwealth it will automatically be considered classified as Pennsylvania Endangered.

Pennsylvania Endangered (§ 45.12)—A classification of plant species that are in danger of extinction throughout most or all of their natural range in this Commonwealth if critical habitat is not maintained or if the species is greatly exploited by man. This classification also includes populations of plant species that have been classified as Pennsylvania Extirpated but are subsequently found to exist in this Commonwealth.

Pennsylvania Threatened (§ 45.13)—A classification of plant species that may become endangered throughout most or all of their natural range in this Commonwealth if critical habitat is not maintained to prevent their further decline, or if the species is greatly exploited by man.

Pennsylvania Rare (§ 45.14)—A classification of plant species that are uncommon in this Commonwealth because they have low population numbers or are only found in restricted geographic areas.

Pennsylvania Vulnerable (§ 45.15)—A classification of plant species that are in danger of population decline in this Commonwealth because of their beauty, economic value, use as a cultivar or other factors which indicate that persons may seek to remove these species from their native habitats.

Special Concern Population (§ 45.20)—A classification of plant species that the Department has determined to be a unique occurrence deserving protection. Among the factors used to classify a plant species as a Special Concern Population are the existence of unusual geographic locations, unisexual populations or extraordinarily diverse plant populations.

Tentatively Undetermined (§ 45.21)—A classification of plant species that are in danger of population decline but do not meet the criteria for any other classification due to taxonomic uncertainties, limited historical records or insufficient data.

Updating species nomenclature

 This proposed rulemaking updates the scientific and common names of certain native wild plant species to conform to the Department's new taxonomic source material.

 The current nomenclature used to identify species taxonomy in Chapter 45 comes from John T. Kartesz's 1980 publication, A Synonymized Checklist of the Vascular Flora of the United States, Canada and Greenland, Volume 2: The Biota of North America. The Department now uses The Plants of Pennsylvania Second Edition (2007) by Ann Fowler Rhoads and Timothy A. Block as a reference. This proposed rulemaking updates the reference to reflect the most up-to-date information on native wild plants in this Commonwealth. This necessitates an update to the scientific and common names in Chapter 45 to remain consistent with the new source material. Additionally, this proposed rulemaking corrects minor grammatical errors and misspellings of species names.

Pennsylvania Natural Diversity Inventory

 The proposed amendments will be incorporated into the Pennsylvania Natural Diversity Inventory (PNDI).

 The PNDI is a database that maintains the Department's list of native wild plant classifications, as well as native rare wildlife classifications from the Game Commission, the Fish and Boat Commission and the United States Fish and Wildlife Service. The PNDI provides the most current, reliable and objective scientific information about ecological resources in this Commonwealth and it is used to help inform environmental decisions in the Commonwealth. Most notably, the Department of Environmental Protection (DEP) uses the PNDI to inform its environmental permitting decisions.

 The overwhelming majority of users use the PNDI as part of the process of obtaining a DEP permit. The DEP requires permit applicants to screen their land use projects through the PNDI for potential impacts to threatened or endangered species to receive a DEP permit; threatened and endangered plant species are thereby protected by the DEP's permitting process.

 Although this proposed rulemaking will result in updates to the plant data in the PNDI, this proposed rulemaking will not affect the DEP's permitting process. The process of obtaining a DEP permit is beyond the scope of this proposed rulemaking. Instead, the PNDI's connection to this proposed rulemaking is limited to its use of the plant data that will result from the proposed amendments. No person, business, small business or organization will be required to invest in additional administrative procedures as a direct result of this proposed rulemaking.

 Finally, because this proposed rulemaking will remove more species from classifications than it adds, there may be fewer classified plant species for prospective DEP permit applicants to account for when applying to obtain DEP permits. Depending on the project type, location and classified plant species in question, prospective DEP permit applicants may see no change in the amount of mitigation required to address impacts to threatened and endangered species and fulfil permit requirements.

E. Summary of this Proposed Rulemaking

Subchapter A. General provisions

 The definition of ''unlisted'' is proposed to be deleted from § 45.2 (relating to definitions) because it is not used in Chapter 45.

 Proposed amendments to § 45.3 (relating to classified plant taxonomy) update the taxonomic source material that the Department uses for the nomenclature of native wild plants from John T. Kartesz and Rosemarie Kartesz, A Synonymized Checklist of the Vascular Flora of the United States, Canada and Greenland, Volume 2: The Biota of North America (1980), to Ann Fowler Rhoads and Timothy A. Block, The Plants of Pennsylvania An Illustrated Manual Second Edition (2007), Philadelphia, Pennsylvania: University of Pennsylvania Press.

Subchapter B. Classified plants

 There are 130 substantive proposed amendments to Subchapter B (relating to classified plants), with 79 proposed name changes and 51 classification changes. The substantive proposed amendments include: 9 currently unclassified plant species proposed to be newly classified; 11 currently classified plant species proposed to be reclassified; 31 currently classified plant species that are proposed to be unclassified; and 79 currently classified plant species with proposed name changes.

 For the purposes of this proposed rulemaking, a substantive name change is one that changes the meaning of the plant name (see the following ''plant name changes'' section). This proposed rulemaking makes minor grammatical corrections to plant names (that is, adding periods, deleting commas and fixing spelling errors) that do not change the meaning of the plant name and are therefore not substantive.

F. Benefits, Costs and Compliance

Benefits

 This proposed rulemaking will benefit State, county and municipal conservation planning officials, conservation groups and other organizations concerned with the welfare of the environment because it more accurately represents the plants in this Commonwealth in need of the most protection. Additionally, this proposed rulemaking benefits the citizens of this Commonwealth by protecting this Commonwealth's natural resources, which is a constitutional right. See Pa.Const. Art. I, § 27.

 Keeping up-to-date classifications of native wild plants, ensures that the Department and other public and private conservation organizations are targeting the appropriate species in their conservation efforts. This will help maintain the biodiversity of ecological systems in this Commonwealth.

Compliance costs

 This proposed rulemaking does not prescribe anything for a group or entity to comply with. This proposed rulemaking updates the Commonwealth's classified lists of native wild plants, updates the scientific and common names of certain native wild plant species, and updates the reference source of the nomenclature that the Department uses for native wild plant species taxonomy. There are no compliance costs associated with this proposed rulemaking.

Paperwork requirements

 There will be no increase in the amount of required paperwork associated with this proposed rulemaking.

G. Sunset Review

Subchapter A. GENERAL PROVISIONS

§ 45.2. Definitions.

 The following words and terms, when used in this chapter, have the following meanings, unless the context clearly indicates otherwise:

*  *  *  *  *

Tentatively Undetermined—A classification of plant species which are believed to be in danger of population decline, but which cannot presently be included within another classification due to taxonomic uncertainties, limited evidence within historical records or insufficient data.

[Unlisted—Plant species which are native to this Commonwealth, presently capable of sustaining their populations successfully, not in need of protection currently and currently not included in classifications under this chapter.]

Wild plants—Naturally occurring native flora, except those commonly considered an agricultural commodity, including green and nongreen species or subspecies, variety or a part, product, seed or progeny thereof.

§ 45.3. Classified plant taxonomy.

 Nomenclature used to identify species taxonomy [contained within Subchapter B is according to Kartesz, J. T. and Rosemarie Kartesz, 1980 A Synonymized Checklist of the Flora of the U. S., Canada, and Greenland] in Subchapter B (relating to classified plants) is according to Rhoads, A. F. and Block, T. A. (2007), The Plants of Pennsylvania An Illustrated Manual Second Edition, Philadelphia, Pennsylvania: University of Pennsylvania Press, unless a different taxonomic source is indicated immediately following the scientific name.
