    HISTORIC RESOURCES IDENTIFICATION STATEMENT OF SIGNIFICANCE Final 6/2/15 - Prepared by Carla Bollinger Chatsworth Nature Preserve/Reservoir Why is this individual resource or neighborhood significant? Chatsworth Nature Preserve (CNP) is a representation of San Fernando Valley (SFV)-Los Angeles history from pre-historic through the 20th Century. This is the last remaining opening space, 1325 acres, on the valley floor with rolling hills, native plants and oak trees, a vision of what the SFV once looked like with numerous cultural-historic landmarks.

  • Sapsucker, Red-Naped
    320 Woodpeckers — Family Picidae Red-naped Sapsucker Sphyrapicus nuchalis Coming from a breeding range in the Great Basin and Rocky Mountain region, the Red-naped Sapsucker reaches San Diego County as an uncommon winter visitor. It occurs most often in oak woodland but shows up occasionally throughout the county. There is no difference in habitat and behavior between the Red-naped and Red-breasted Sapsuckers here, and the former is only slightly less numerous than the latter. In the lack of previous summer records from southern California, one of the greatest surprises of the atlas field work was three summer observa- tions of the Red-naped Sapsucker from Palomar Mountain, including one of hybridization with the Red-breasted.

Passing oxcarts, Tractors hauling cane, and numerous old cars in various states of maintenance and care, participants made their way to one of the two Hotels in Cuba recently affiliated with larger world chain operations. While this might seem to be a bit of an odd juxtaposition to the indigenous parochial surroundings, the locals seem very excited to have the recent influx of foreign interest and monies to update and improve the local infrastructure, including this fine hotel. With the Russian embassy building dominating the skyline (a bizarre, monolithic, imposing structure indeed!) from our balconies, and the Caribbean on the horizon, we enjoyed the best Western Spindalis by Dušan Brinkhuizen accommodations in the city.

  • Habitat Selection by Red-Breasted Sapsucker (Sphyrapicus
    HABITAT SELECTION BY RED-BREASTED SAPSUCKER (SPHYRAPICUS RUBER) IN SOUTHEAST ALASKA OLD-GROWTH FOREST by Marlene A. Wagner A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment Of the Requirements for the Degree Master of Science In Natural Resources: Wildlife March, 2011 ABSTRACT Habitat Selection by Red-breasted Sapsucker (Sphyrapicus ruber) in Southeast Alaska Old-Growth Forest Marlene A. Wagner Conservation of a keystone species requires knowledge of habitat use across the species’ range. The factors that influence habitat selection by Red-breasted Sapsucker (Sphyrapicus ruber) in the temperate rainforests of southeast Alaska are poorly understood. I examined habitat selection of this keystone species during the breeding season in 2008 and 2009. I quantified the structural characteristics of sapwell trees and compared them to trees without sapwells, and I located nests to describe nest trees and compare characteristics of used and available nest trees and nest sites using model selection techniques. Sapsuckers selected trees for building sapwells that were intermediate in size, had high bark furrow depth, and had a greater incidence of conks and dwarf mistletoe. Nesting Sapsuckers did not show bias for cavity orientation and nest trees were predicted primarily by size and the presence of fungal infection at intermediate stages of decay. Nest sites contained a lower volume of trees, higher DBH, increased incidence of fungal infection, and older decay classes of coarse woody debris than available sites. These findings suggest that during the breeding season, Red- breasted Sapsuckers select habitats with attributes characteristic of the full range of old- growth forest succession, and they therefore may need substantial forest structural diversity for their feeding and nesting activities.

As participants arrived, they were shuttled from the airport to our hotel in Havana. After lunch at our hotel, we visited Alamar Organoponico Gardens, an organic farm outside Havana that supplies produce to many Havana-area restaurants. We spotted a few birds during our tour of the farm, including Smooth-billed Ani, Cattle Egret, Turkey Vulture, Cuban Emerald, Scaly-breasted Munia, Palm Warbler and Greater Antillean Grackle. Except for the munias, we would see these birds on an almost daily basis. We returned to our hotel just before a rainstorm moved through the city.

  • Whats That EAB Only.Pdf
    What’s that?! You have learned a little bit about emerald ash borer and want to put your knowledge to the test! What’s that?! is a series of 10 stations with scenarios and photos all about the emerald ash borer, native look-a-likes, and more. Each scenario allows students to put their knowledge to the test and see what they would do in that situation. Each station has an answer included. Station 1 Trish Hanson, entomologist with Forest, Parks & Recreation, asks you to respond to a call about stressed ash trees on a property in your town. You take a look and, as you approach the tree, you notice brown leaves. When you get closer, you notice the following holes in the bark. How do you respond? Station 1: Answer The ash tree does seem to have many of the signs and symptoms of the emerald ash borer including exit holes. However, when examined closely, these exit holes are completely circular. They do not have the diagnostic D-shape exit hole (at right) that emerald ash borer creates. These exit holes are likely from the eastern ash bark beetle. More about the ash bark beetle: Adults overwinter in tunnels under the bark of infested branches. In the spring, females begin constructing egg galleries in trees that are typically recently felled or weakened host trees. The egg galleries run perpendicular to the branch or trunk. Eggs are laid along the sides of the galleries. Larvae tunnel between the bark and the wood throughout the summer, feeding away from the egg gallery.

  • Sapsucker Damage and Management by E
    RESEARCH LABORATORY TECHNICAL REPORT Sapsucker Damage and Management By E. Thomas Smiley, Ph.D. and Beth Brantley, Ph.D. Sapsuckers (Sphyrapicus) are species of woodpeckers that feed primarily on the sap of trees and shrubs. The yellow- bellied sapsucker is found in the eastern United States and Canada while the red-breasted, red-naped, and Williamson’s sapsuckers are found in the western United States (Figure 1). Many sapsuckers are migratory, spending summer in the north and winter in the south. Sapsuckers feed on over 1,000 species of trees and shrubs. In the eastern United States, thin-barked species with high sugar content in the sap, such as birch and maple, are preferred hosts. Damage Figure 1: Yellow-bellied sapsucker attacking a Sapsuckers produce sap flow by excavating small holes red maple in the trunks and branches of woody plants, creating sapwells in the phloem and xylem (Figure 2). Each sapwell is about 0.25 inches (4-6 mm) in diameter. Sapsucker damage is characterized by horizontal rows of sapwells. The sap may attract insects on which sapsuckers and other birds feed. Fungi growing on the sugary liquid frequently stain bark below sapwells. If the sapwells are left unattended by the woodpecker for a few days, sap flow may slow or stop. A few scattered rows of sapwells will not typically cause significant damage. However, trees repeatedly and heavily attacked may be damaged, resulting in Figure 2: Sapwells on a sugar maple. Light colored sapwood can be seen at the bottom of the well. reduced growth, increased likelihood for tree failure, Some sapwells are flowing.
