Ecosystem Restoration Guide for Pine Barrens (Drylands)
Ecosystem Management and Restoration Planning Guide: Drylands USDA - Natural Resources Conservation Service, Durham, NH Alan P. Ammann Ph.D., Biologist Dry (Xeric) forest near Keene airport. Note pitch pine in right foreground and little bluestem in opening. NRCS Natural Resources Conservation Service (603) 868-7581 - www.nh.nrcs.usda.gov Ammann, A. P. - DRAFT 03/31/00 1 PURPOSE OF THIS DOCUMENT The purpose of this document is to provide guidance for planning ecosystem management and restoration projects in saline tidal wetlands in New Hampshire. It is intended for professional environmental planners including NRCS field office personnel. It may also be useful as an educational tool for interested laypersons including members of town Conservation Commissions. Non professional uses of this document are cautioned that ecosystem restoration requires professional judgement based on education and experience. GEOGRAPHIC AREA TO WHICH THIS DOCUMENT APPLIES This document is intended for New Hampshire. Knowledgeable persons can apply it to New England. Many of the principles and structure of this document can be adapted to other areas of the United States ECOSYSTEM DESCRIPTION Drylands are those portions of the New Hampshire landscape that typically have low available soil moisture due to their coarse textures soils and position in the landscape. Under natural conditions fire dependent sub-climax communities (Pine Barrens and native grasslands) occur as a patchwork within a matrix of white pine (Pinus strobus L.) and mixed hardwood dry forest matrix. The sub-climax communities arise in the open sunny conditions following fire and are dominated by pitch pine (Pinus rigida Miller), red pine (Pinus resinosa Aiton) and to the north by jack pine (Pinus banksiana Lambert). -

Holmes [email protected] Department of Biology Baylor University Waco, Texas Introduction This document has been produced to serve as a quick guide to the identification of milkweeds (Asclepias spp.) in Texas. For the species listed in Table 1 below, basic information such as range (in this case county distribution), habitat, and key identification characteristics accompany a photograph of each species. This information comes from a variety of sources that includes the Manual of the Vascular Flora of Texas, Biota of North America Project, knowledge of the authors, and various other publications (cited in the text). All photographs are used with permission and are fully credited to the copyright holder and/or originator. Other items, but in particular scientific publications, traditionally do not require permissions, but only citations to the author(s) if used for scientific and/or nonprofit purposes. Names, both common and scientific, follow those in USDA NRCS (2015). When identifying milkweeds in the field, attention should be focused on the distinguishing characteristics listed for each species. -

New Jersey Tea Ceanothus Americanus L
New Jersey tea Ceanothus americanus L. Group: Dicot Family: Rhamnaceae (buckthorn) Growth Habit: Subshrub/shrub Duration: Perennial U.S. Nativity: Native to much of eastern U.S. Natural Enemies Attracted: Small numbers of Thomisidae, Chalcidoidea, Syrphidae, Empididae, Orius insidiosus, Braconidae and Cynipoidea. Pests Attracted: Large number of lygus bugs. Small number of thrips, leafhoppers, root- maggot flies and aphids. Bees attracted: Low numbers (less than 1 bee per meter square in a 30 second sample) of bees including yellow-faced bees and sweat bees. Species Notes: Airy white flower clusters bloom on plants that grew 2-3 feet tall. Plants were slow to establish, but in their fourth year of growth filled in and bloomed prolifically. Plants bloomed in early July. This species was the fourth least attractive to natural enemies in the mid season, with half as many natural enemies as the grass control.

BACKGROUND and PURPOSE In an effort to encourage the protection of native Maine plants that are naturally reduced or low in number, the State Planning Office has compiled a list of endangered and threatened plants. Of Maine's approximately 1500 native vascular plant species, 155, or about 10%, are included on the Official List of Maine's Plants that are Endangered or Threatened. Of the species on the list, three are also listed at the federal level. The U.S. Fish and Wildlife Service. has des·ignated the Furbish's Lousewort (Pedicularis furbishiae) and Small Whorled Pogonia (lsotria medeoloides) as Endangered species and the Prairie White-fringed Orchid (Platanthera leucophaea) as Threatened. Listing rare plants of a particular state or region is a process rather than an isolated and finite event. -

The Pennsylvania State University The Graduate School School of Science, Engineering, and Technology IMPACT OF OZONE ON MILKWEED (ASCLEPIAS) SPECIES A Thesis in Environmental Pollution Control by Abigail C. Myers 2016 Abigail C. Myers Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science December 2016 The thesis of Abigail C. Myers was reviewed and approved* by the following: Dennis R. Decoteau Professor of Horticulture and Plant Ecosystem Health Thesis Advisor Donald D. Davis Professor of Plant Pathology and Environmental Microbiology Richard Marini Professor of Horticulture Shirley Clark Associate Professor of Environmental Engineering Graduate Program Coordinator, Environmental Engineering and Environmental Pollution Control *Signatures are on file in the Graduate School ii Abstract Tropospheric (or ground level) ozone in ambient concentrations can damage vegetation and interfere with the human respiratory system. Plants as bioindicators of ozone are commonly used to detect phytotoxic levels of tropospheric ozone where physical/chemical/electrical monitoring equipment cannot be utilized due to expense, electrical needs, or availability of instruments. Asclepias syriaca (Common Milkweed) has been effectively used as a bioindicator for ozone. Visual ozone injury on Common Milkweed is characterized as purple stippling of the upper surface of older leaves as the season progresses, the purple coloration of the upper leaf surface may encompass most of the leaf surface. While sensitivity to ozone has been documented on Common Milkweed, less is known about the ozone sensitivity of other Asclepias species and little is known regarding the concentration dose response of Common Milkweed to ozone and timing of visual symptoms. Of the Asclepias species evaluated Tropical Milkweed (A. -

Shimek: The Prairie of the Mississippi River Bluffs THE PRAIRIE OF THE MISSISSIPPI RIVER BLUFFS BY B. SHIMEK The rugged bluffs along the upper Mississippi river, particularly those which border that part of the river flowing between Iowa and \Visconsin, display irregular treeless tracts on their slopes which are sure to attract the attention of observers who travel along the river either by water or by land. Very few of these treeless areas on the more rugged bluffs are artificial clearings. The great majority are natural openings, and there is no evidence to show that they were ever covered with forest. On the contrary, their location indicates that the absence of trees is due to natural causes, and that they are of long standing. The student of plants is soon impressed with the fact that not only are trees absent from these areas, but that the smaller plants, mostly herbs, which cover them belong very distinctly to the prairie flora. -

The gorgeous golden-brown and black but- terfly is probably the most celebrated insect on the continent, and the migration of the eastern population is conspicuous and spectacular. Southbound Monarchs can appear anywhere, even in highly urban- ized locales, and the butterflies often use backyard gardens as way sta- tions. Occasionally a resting swarm of hundreds or even thousands of butterflies is encountered. The spectacle of trees dripping with living leaves of butterflies is unlikely to be forgotten.
