An increasing need for careful husbandry of the earths natural resources has renewed interest
in the classification and mapping of ecosystems. The inventory of our remaining biotic entities is particularly urgent because the increased aspirations of a constantly growing world population
are placing ever greater stress on these generous, but finite, living resources.

To know the desert involves an acquaintance
with all its aspects, and all its physical features,
as well as all of the animals and plants that
have learned how to find in it a congenial place to live. The
most significant lesson that the desert
dweller can learn from a familiarity with its plant and animal life is to
regard
himself not as an exile from some better place, but as a man at home in an
environment to which his life can be adjusted without physical or intellectual
loss. Forest Shreve, The Cactus and
Its Home (Found in Discovering the Desert, by William G. McGinnies)

SPECIES DISTRIBUTION LISTINGS
Species Distribution Listings are being developed to encourage and promote the conservation of local native animals and plants. Species Distribution Listings are developed for legally defined geographic areas, and larger bodies of water. Listings include species reported as having been observed in or reported from the described area. Due to continuing additions and corrections the listings should be considered works in progress. The source(s) used for the inclusion of the species in a listing is highlighted in green *00* in the footnotes. Due to the lack of first hand knowledge, in the listing of animals, unless otherwise noted in the footnotes, species may be included based on general distribution maps and/or statements and not on an actual sight record. I recommend that we consider a species as being confirmed to a township or general listing area only after we have at least three recorded sightings, cited in the footnotes, with no more than one of those records being based on general distribution mapping for the species. Note that the Southwest Environmental Information Network (SEINet) *85* may have several collections recorded for a species within any given township or listing area, and that the date shown in parentheses is a date of the search of their records and not a date of recorded sighting. Note also that many of the individual species collection records found in SEINet include additional associated species.
Individual species records are presented alphabetically by division, class, family and genus within their kingdoms. Following the scientific name is the authority, common synonym(s), common name(s), a general description of the species habitat, the biotic communities in which it has reportedly been observed and footnotes. An attempt is being made to identify the range in mature (flowering/fruiting) heights reported for the plants. The habitat description is provided in order to help you visualize the types of natural habitats the species is found in and ones in which it might be planted back into in a landscape or restoration project. The range in elevation has been rounded off to the nearest 100 feet up, for the higher elevation or down, for the lower elevation. Species reported from within 0 to 100 feet as their lower elevation limit have been recorded as occurring from sea level. Species once reported as having occurred within the described area, but that no longer occurs there are shown are having been EXTIRPATED. This list includes species that are not native to Arizona (EXOTIC). Exotic plants are not recommended for use in landscaping or restoration projects. Disjunct species, outliers and plants on the edge of the main population, as observed by the surveyor, may be noted as being PERIPHERAL PLANT(S). Landscaped plants are not included in the listings unless they have become naturalized into the surrounding native environment.
Local native plants are recommended for use in landscape and restoration projects. Many native species require little, if any, irrigation once established. Ideally restoration should include those plants that were native to the property prior to clearing. In order to determine what plants were native to the property you might try to locate photographs of the property prior to clearing or look for natural areas and remnant populations and plants adjacent to where the restoration is to take place. Plants should be planted in their approximate original habitat and density.
The use of native plants in landscape and restoration projects encourages native animals to remain in the area and helps to retain the areas natural beauty and unique identity and heritage.
Species Distribution Lists are periodically updated and revised. These listings have been created and maintained by William T. Kendall. Questions, concerns, corrections and comments, including the reporting of unrecorded species and information relating to historical distributions, may be sent to the following address: Kendall Environmental Surveys, P.O. Box 86091, Tucson, Arizona 85754-6091, or E-mail to:KendallEnvironmentalSurveys@msn.com.
DISCLAIMER: The information presented as township notes has been obtained from large scale mapping and should be used only as a general guide. These listings are not meant to take the place of on-site surveys for species. Information used in these lists is accepted from biologists and individuals interested in helping to promote the conservation of our natural resources. Mistakes are made in the identification of species and in the recording of information, and changes in nomenclature occur. For these reasons I can not and do not warrant the accuracy of these listings. Attempts are made to keep the information contained in the Species Distribution Listings as accurate as possible, but Kendall Environmental Surveys disclaims any implied warranty or representation about its accuracy, completeness, or appropriateness for any particular purposes. Users of the information found in the listings assume full responsibility for their use of the information and understand that Kendall Environmental Surveys is not responsible or liable for any claim, loss, or damage resulting from its use.
CAUTION: Many native desert plants have sharp thorns and spines. Care should be given when handling these plants and consideration should be given to public safety at sites where they are to be planted. Range plants having a known toxic or poisonous property may be so noted. Footnotes for plants whose sources may have cautionary statements, comments and information on rarely poisonous or suspected poisonous range plants may be shown in red (*00*). Many poisonous plants are similar in appearance to edible ones. No field collected plant should be eaten unless you know for a fact that it is safe for you to do so.

owners involved in the clearing of land allow for nurseries and people who are
interested in salvaging plants to do so prior to the clearing. The Arizona
Department of Agriculture posts these notifications in their county offices.
You may also contact the Arizona Department of Agriculture and, for a fee, be
put on a mailing list of people receiving copies of the Notices of Intent to Clear
Land.
