SALT TOLERANT PLANTS Recommended for Pender County Landscapes
North Carolina Cooperative Extension NC STATE UNIVERSITY SALT TOLERANT PLANTS Recommended for Pender County Landscapes Pender County Cooperative Extension Urban Horticulture Leaflet 14 Coastal Challenges Plants growing at the beach are subjected to environmental conditions much different than those planted further inland. Factors such as blowing sand, poor soils, high temperatures, and excessive drainage all influence how well plants perform in coastal landscapes, though the most significant effect on growth is salt spray. Most plants will not tolerate salt accumulating on their foliage, making plant selection for beachfront land- scapes particularly challenging. Salt Spray Salt spray is created when waves break on the beach, throwing tiny droplets of salty water into the air. On-shore breezes blow this salt laden air landward where it comes in contact with plant foliage. The amount of salt spray plants receive varies depending on their proximity to the beachfront, creating different vegetation zones as one gets further away from the beachfront. The most salt-tolerant species surviving in the frontal dune area. As distance away from the ocean increases, the level of salt spray decreases, allowing plants with less salt tolerance to survive. Natural Protection The impact of salt spray on plants can be lessened by physically blocking salt laden winds. This occurs naturally in the maritime forest, where beachfront plants protect landward species by creating a layer of foliage that blocks salt spray. It is easy to see this effect on the ocean side of maritime forest plants, which are “sheared” by salt spray, causing them to grow at a slant away from the oceanfront. -

© 2020 Theodore Payne Foundation for Wild Flowers & Native Plants. No
April 24, 2020 Theodore Payne Foundation’s Wild Flower Hotline is made possible by donations, memberships and sponsors. You can support TPF by shopping the online gift store as well. A new, pay by phone, contactless plant pickup system is now available. Details here. Widespread closures remain in place. If you find an accessible trail, please practice social distancing precautions. The purpose for the Wild Flower Hotline now is NOT to send you out to localities to view wild flowers, but to post photos that assure you—virtually—that California’s wild spaces are still open for business for flowers and their pollinators. This week Mother Nature turned on the furnace and with the hot temperatures, our spring love fest with the beloved California poppy will soon come to an end. Throughout the state, poppies are setting both seed and promise for a glorious Spring 2021. Antelope Valley and the surrounding area has a great display of luminous orange California poppies (Eschscholzia californica), electric yellow monolopia (Monolopia lanceolata) and patches of goldfields (Lasthenia sp.). Spotted among the overwhelming yellow-orange color, are lupine (Lupinus spp.), tansy leafed phacelia (Phacelia tanacetifolia) and popcorn flower (Cryptantha spp.). You do not need to leave your home to see the poppies at the Antelope Valley State Poppy Reserve. Just view the live stream online at the preserve via the PoppyCam.

What Is a Tree in the Mediterranean Basin Hotspot? a Critical Analysis
Médail et al. Forest Ecosystems (2019) 6:17 https://doi.org/10.1186/s40663-019-0170-6 RESEARCH Open Access What is a tree in the Mediterranean Basin hotspot? A critical analysis Frédéric Médail1* , Anne-Christine Monnet1, Daniel Pavon1, Toni Nikolic2, Panayotis Dimopoulos3, Gianluigi Bacchetta4, Juan Arroyo5, Zoltán Barina6, Marwan Cheikh Albassatneh7, Gianniantonio Domina8, Bruno Fady9, Vlado Matevski10, Stephen Mifsud11 and Agathe Leriche1 Abstract Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-European region (from Portugal to Cyprus). We identified some cases of woody species difficult to categorize as trees that we further called “cryptic trees”. We collected the occurrences of tree taxa by “administrative regions”, i.e. country or large island, and by biogeographical provinces. We studied the species-area relationship, and evaluated the conservation issues for threatened taxa following IUCN criteria. Results: We identified 245 tree taxa that included 210 species and 35 subspecies, belonging to 33 families and 64 genera. It included 46 endemic tree taxa (30 species and 16 subspecies), mainly distributed within a single biogeographical unit. -
Artemisia Californica Less
I. SPECIES Artemisia californica Less. [Updated 2017] NRCS CODE: Subtribe: Artemisiinae ARCA11 Tribe: Anthemideae (FEIS CODE: Family: Asteraceae ARCAL) Order: Asterales Subclass: Asteridae Class: Magnoliopsida flowering heads spring growth seedling, March 2009 juvenile plant photos A. Montalvo flowering plant, November 2005 mature plant with flower buds August 2010 A. Subspecific taxa None. Artemisia californica Less. var. insularis (Rydb.) Munz is now recognized as Artemisia nesiotica P.H. Raven (Jepson eFlora 2017). B. Synonyms Artemisia abrotanoides Nuttall; A. fischeriana Besser; A. foliosa Nuttall; Crossostephium californicum (Lessing) Rydberg (FNA 2017). C. Common name California sagebrush. The common name refers to its strong, sage-like aroma and endemism to California and Baja California. Other names include: coastal sage, coast sage, coast sagebrush (Painter 2016). D. Taxonomic relationships The FNA (2017) places this species in subgenus Artemisia . The molecular phylogeny of the genus has improved the understanding of relationships among the many species of Artemisia and has, at times, placed the species in subgenus Tridentadae; morphology of the inflorescences and flowers alone does not place this species with its closest relatives (Watson et al. 2002). The detailed phylogeny is not completely resolved (Hayat et al. 2009). E. Related taxa in region There are 18 species and a total of 31 taxa (including infrataxa) of Artemisia in southern California, all of which differ clearly from A. californica in habitat affinity, structure, or both (Munz 1974, Jepson eFlora 2017). Within subgenus Artemisia (as per FNA 2017), A. nesiotica from the Channel Islands is the most similar and was once considered part of A. californica ; it can be distinguished by its wider leaves with flat leaf margins (not rolled under). -

CDFG Natural Communities List
Department of Fish and Game Biogeographic Data Branch The Vegetation Classification and Mapping Program List of California Terrestrial Natural Communities Recognized by The California Natural Diversity Database September 2003 Edition Introduction: This document supersedes all other lists of terrestrial natural communities developed by the Natural Diversity Database (CNDDB). It is based on the classification put forth in “A Manual of California Vegetation” (Sawyer and Keeler-Wolf 1995 and upcoming new edition). However, it is structured to be compatible with previous CNDDB lists (e.g., Holland 1986). For those familiar with the Holland numerical coding system you will see a general similarity in the upper levels of the hierarchy. You will also see a greater detail at the lower levels of the hierarchy. The numbering system has been modified to incorporate this richer detail. Decimal points have been added to separate major groupings and two additional digits have been added to encompass the finest hierarchal detail. One of the objectives of the Manual of California Vegetation (MCV) was to apply a uniform hierarchical structure to the State’s vegetation types. Quantifiable classification rules were established to define the major floristic groups, called alliances and associations in the National Vegetation Classification (Grossman et al. 1998). In this document, the alliance level is denoted in the center triplet of the coding system and the associations in the right hand pair of numbers to the left of the final decimal. The numbers of the alliance in the center triplet attempt to denote relationships in floristic similarity. For example, the Chamise-Eastwood Manzanita alliance (37.106.00) is more closely related to the Chamise- Cupleaf Ceanothus alliance (37.105.00) than it is to the Chaparral Whitethorn alliance (37.205.00). -
Plant Pest Risk Assessment for Paterson's Curse
Oregon Department of Agriculture Plant Pest Risk Assessment for Paterson’s Curse, Echium plantagineum 2004 (Revised 2010) Name: Paterson’s curse, salvation Jane, Echium plantagineum Family: Borage, Boraginaceae Findings of This Review and Assessment: Paterson’s curse has been determined to be a category of an “A” listed noxious weed as defined by the Oregon Department of Agriculture (ODA) Noxious Weed Policy and Classification System. This determination is based on a literature review and analysis using two ODA evaluation forms. Using the Noxious Qualitative Weed Risk Assessment v.3.8, Paterson’s curse scored 69 indicating an “A” and a score of 17 with the Noxious Weed Rating System v.3.2. Paterson’s curse is one of the highest ranked weeds due to its drought tolerance, ease of spread and impacts on agriculture. Introduction: Paterson’s curse is a showy ornamental named for the Paterson family of southern Australia who allegedly introduced the plant in the 1800’s as a garden ornamental. Since then, the plant has spread over millions of acres in New South Wales, Western Australia and Victoria provinces. Annual losses for livestock producers are estimated at $30 million annually (Smyth 1999). To some producers it is considered a blessing. Early season growth contains high levels of protein and the species does provide forage during dry years when other forage is limited. Older growth though is far less palatable and competes for water with more valuable grass forage species. In Oregon, Echium p. was first identified in 2003 by an Oregon farmer, at a site one mile north of Lebanon in Linn County. -
