Pinus Sabiniana) in Oregon Frank Callahan PO Box 5531, Central Point, OR 97502
Discovering Gray Pine (Pinus sabiniana) in Oregon Frank Callahan PO Box 5531, Central Point, OR 97502 “Th e tree is remarkable for its airy, widespread tropical appearance, which suggest a region of palms rather than cool pine woods. Th e sunbeams sift through even the leafi est trees with scarcely any interruption, and the weary, heated traveler fi nds little protection in their shade.” –John Muir (1894) ntil fairly recently, gray pine was believed to be restricted to UCalifornia, where John Muir encountered it. But the fi rst report of it in Oregon dates back to 1831, when David Douglas wrote to the Linnaean Society of his rediscovery of Pinus sabiniana in California. In his letter from San Juan Bautista, Douglas claimed to have collected this pine in 1826 in Oregon while looking for sugar pine (Pinus lambertiana) between the Columbia and Umpqua rivers (Griffin 1962). Unfortunately, Douglas lost most of his fi eld notes and specimens when his canoe overturned in the Santiam River (Harvey 1947). Lacking notes and specimens, he was reluctant to report his original discovery of the new pine in Oregon until he found it again in California (Griffin 1962). Despite the delay in reporting it, Douglas clearly indicated that he had seen this pine before he found it in California, and the Umpqua region has suitable habitat for gray pine. John Strong Newberry1 (1857), naturalist on the 1855 Pacifi c Railroad Survey, described an Oregon distribution for Pinus sabiniana: “It was found by our party in the valleys of the coast ranges as far north as Fort Lane in Oregon.” Fort Lane was on the eastern fl ank of Blackwell Hill (between Central Point and Gold Hill in Jackson County), so his description may also include the Th e lone gray pine at Tolo, near the old Fort Lane site, displays the characteristic architecture of multiple Applegate Valley. -

Within the great diversity of pines in Mexico, Pinus culminicola Andresen et Beaman, P. jaliscana Perez de la Rosa, P. maximartinenzii Rzed., P. nelsonii Shaw, P. pinceana Gordon, and P. rzedowskii Madrigal et M. Caball. are six catalogued as threatened or endangered due to their restricted distribution and low population density. Therefore, they are of special interest for forest conservation purposes. In this paper, we aim to provide up-to-date information on the spatial distribution of these six pine species according to different historical registers coming from different herbaria distributed around the country by using spatial modeling. Therefore, we recovered historical observations of the natural distribution of each species and modelled suitable areas of distribution according to environmental requirements. Finally, we evaluated the distributions by contrasting changes of vegetation in the period 1991–2016. -

Ecosystems and Diversity of the Sierra Madre Occidental
Ecosystems and Diversity of the Sierra Madre Occidental M. S. González-Elizondo, M. González-Elizondo, L. Ruacho González, I.L. Lopez Enriquez, F.I. Retana Rentería, and J.A. Tena Flores CIIDIR I.P.N. Unidad Durango, Mexico Abstract—The Sierra Madre Occidental (SMO) is the largest continuous ignimbrite plate on Earth. Despite its high biological and cultural diversity and enormous environmental and economical importance, it is yet not well known. We describe the vegetation and present a preliminary regionalization based on physio- graphic, climatic, and floristic criteria. A confluence of three main ecoregions in the area corresponds with three ecosystems: Temperate Sierras (Madrean), Semi-Arid Highlands (Madrean Xerophylous) and Tropical Dry Forests (Tropical). The Madrean region harbors five major vegetation types: pine forests, mixed conifer forests, pine-oak forests, oak forests and temperate mesophytic forests. The Madrean Xerophylous region has oak or pine-oak woodlands and evergreen juniper scrub with transitions toward the grassland and xerophylous scrub areas of the Mexican high plateau. The Tropical ecosystem, not discussed here, includes tropical deciduous forests and subtropical scrub. Besides fragmentation and deforestation resulting from anthropogenic activities, other dramatic changes are occurring in the SMO, including damage caused by bark beetles (Dendroctonus) in extensive areas, particularly in drought-stressed forests, as well as the expansion of chaparral and Dodoneaea scrub at the expense of temperate forest and woodlands. Comments on how these effects are being addressed are made. Introduction as megacenters of plant diversity: northern Sierra Madre Occidental and the Madrean Archipelago (Felger and others 1997) and the Upper The Sierra Madre Occidental (SMO) or Western Sierra Madre is the Mezquital River region (González-Elizondo 1997). -

Evidence from Three Mexican Species
Color profile: Generic CMYK printer profile Composite Default screen 131 Do rare pines need different conservation strategies? Evidence from three Mexican species Francisco Molina-Freaner, Patricia Delgado, Daniel Piñero, Nidia Perez-Nasser, and Elena Alvarez-Buylla Abstract: Mexico is a major center of diversity for the genus Pinus as it has the greatest number of species in the world. Many species are now restricted to Mexico, and some are represented by very small populations and are in dan- ger of extinction. In this study we examined allozyme variation in three rare species of Mexican pines: Pinus pinceana Gord., Pinus lagunae M.F. Passini, and Pinus muricata D. Don, with the objective of providing conservation guide- lines. The three species had relatively high levels of genetic variation with mean expected heterozygosities of 0.373, 0.386, and 0.346 for P. pinceana, P. lagunae, and P. muricata, respectively. We found marked differentiation among populations and significant inbreeding within populations of the three species. These values are larger than the range reported for most conifers and suggest that conservation strategies of these rare pines require focusing on the viability of several populations. Given that our knowledge about the demographic status of the three species is scarce, we pro- pose a mixed strategy of conservation. For P. lagunae, we propose an in situ strategy, whereas for P. pinceana and P. muricata we propose an ex situ strategy of conservation until permanent protection can be provided for several of their populations. Key words: genetic structure, conservation, rare pines, Pinus pinceana, Pinus lagunae, Pinus muricata. -

Mistletoes of North American Conifers
United States Department of Agriculture Mistletoes of North Forest Service Rocky Mountain Research Station American Conifers General Technical Report RMRS-GTR-98 September 2002 Canadian Forest Service Department of Natural Resources Canada Sanidad Forestal SEMARNAT Mexico Abstract _________________________________________________________ Geils, Brian W.; Cibrián Tovar, Jose; Moody, Benjamin, tech. coords. 2002. Mistletoes of North American Conifers. Gen. Tech. Rep. RMRS–GTR–98. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 123 p. Mistletoes of the families Loranthaceae and Viscaceae are the most important vascular plant parasites of conifers in Canada, the United States, and Mexico. Species of the genera Psittacanthus, Phoradendron, and Arceuthobium cause the greatest economic and ecological impacts. These shrubby, aerial parasites produce either showy or cryptic flowers; they are dispersed by birds or explosive fruits. Mistletoes are obligate parasites, dependent on their host for water, nutrients, and some or most of their carbohydrates. Pathogenic effects on the host include deformation of the infected stem, growth loss, increased susceptibility to other disease agents or insects, and reduced longevity. The presence of mistletoe plants, and the brooms and tree mortality caused by them, have significant ecological and economic effects in heavily infested forest stands and recreation areas. These effects may be either beneficial or detrimental depending on management objectives. Assessment concepts and procedures are available. Biological, chemical, and cultural control methods exist and are being developed to better manage mistletoe populations for resource protection and production.
