    SUMMER 2018 mprpd.org Monterey Peninsula Regional Park District LET’S GO CELEBRATING 10 YEARS! OUTDOORS! Your adventure activities guide for all ages Preserving and Protecting Parks and Open Space AMessagefromtheGeneralManager Dear Friends, The greatest challenges sometimes create the greatest opportunities, resulting in the greatest outcomes. Such was the case when private land owners, the community, The Trust for Public Land, Santa Lucia Conservancy (SLC), Trout Unlimited, Welcome State of California, County of Monterey, Monterey Peninsula Regional Park District (MPRPD), and others combined their vision and work to create the Rancho Cañada unit of Palo Corona Regional Park from the former Rancho Cañada Golf Club. In April, The Trust for Public Land transferred ownership of the property to the residents and visitors of the Central Coast. SLC Executive Director Christy Fischer stated, “From the beginning, this project has been about a community coming together around a shared vision.” MPRPD’s acquisition of Rancho Cañada will facilitate one of the nation’s most significant environmental and cultural resource restoration, preservation and conservation projects. “As this new parkland is restored to improve the health and future of our river, native plants and wildlife, I hope it will also be a place where visitors can learn about and celebrate the ways and wisdom of its first people. It is a great gift to us all.” - Linda Yamane, Rumsen Ohlone Tribal historian “The land had been in our family since the late 1800s. Protecting the land and preserving it for future generations is my family’s way of showing tribute to my great-grandfather, William Hatton.

  • Foundation Document Overview, Pinnacles National Park, California
    NATIONAL PARK SERVICE • U.S. DEPARTMENT OF THE INTERIOR Foundation Document Overview Pinnacles National Park California Contact Information For more information about the Pinnacles National Park Foundation Document, contact: [email protected] or (831) 389-4485 or write to: Superintendent, Pinnacles National Park, 5000 Highway 146, Paicines, CA 95043 Fundamental Resources and Values Interpretive Themes Fundamental resources and values are those features, systems, processes, experiences, stories, scenes, sounds, smells, or other attributes determined to merit primary consideration during planning and management processes because they are essential to achieving the purpose of the park and maintaining its significance. The following fundamental resources and values have been identified for Pinnacles National Park: • Landforms and Geologic Faults Reflecting Past and Present Tectonic Forces • Scenic Views and Wild Character • Talus Caves Photo by Paul G. Johnson • Opportunities for Research and Study • Native Species and Ecological Processes Interpretive themes are often described as the key stories or concepts that visitors should understand after visiting a park—they define the most important ideas or concepts communicated to visitors about a park unit. Themes are derived from—and should reflect—park purpose, significance, resources, and values. The set of interpretive themes is complete when it provides the structure necessary for park staff to develop opportunities for visitors to explore and relate to all of the park significances and fundamental resources and values. • Over millions of years, the power of volcanism, erosion, and plate tectonics created and transformed the Pinnacles Volcanic Field into the dramatic canyons, monoliths, and rock spires seen today. The offset of the Pinnacles Volcanics from the identical Neenach Volcanics 200 miles to the south provides key evidence for the theory of plate tectonics.

  • Life History Account for Peregrine Falcon
    California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group PEREGRINE FALCON Falco peregrinus Family: FALCONIDAE Order: FALCONIFORMES Class: AVES B129 Written by: C. Polite, J. Pratt Reviewed by: L. Kiff Edited by: L. Kiff DISTRIBUTION, ABUNDANCE, AND SEASONALITY Very uncommon breeding resident, and uncommon as a migrant. Active nesting sites are known along the coast north of Santa Barbara, in the Sierra Nevada, and in other mountains of northern California. In winter, found inland throughout the Central Valley, and occasionally on the Channel Islands. Migrants occur along the coast, and in the western Sierra Nevada in spring and fall. Breeds mostly in woodland, forest, and coastal habitats. Riparian areas and coastal and inland wetlands are important habitats yearlong, especially in nonbreeding seasons. Population has declined drastically in recent years (Thelander 1975,1976); 39 breeding pairs were known in California in 1981 (Monk 1981). Decline associated mostly with DDE contamination. Coastal population apparently reproducing poorly, perhaps because of heavier DDE load received from migrant prey. The State has established 2 ecological reserves to protect nesting sites. A captive rearing program has been established to augment the wild population, and numbers are increasing (Monk 1981). SPECIFIC HABITAT REQUIREMENTS Feeding: Swoops from flight onto flying prey, chases in flight, rarely hunts from a perch. Takes a variety of birds up to ducks in size; occasionally takes mammals, insects, and fish. In Utah, Porter and White (1973) reported that 19 nests averaged 5.3 km (3.3 mi) from the nearest foraging marsh, and 12.2 km (7.6 mi) from the nearest marsh over 130 ha (320 ac) in area.

Variation in syringealmorphology was studied to resolve the relationshipsof representativesof all of the recognized genera of falcons, falconets, pygmy falcons, and caracarasin the family Falconidae. The phylogenyderived from thesedata establishesthree major cladeswithin the family: (1) the Polyborinae, containingDaptrius, Polyborus, Milvago and Phalcoboenus,the four genera of caracaras;(2) the Falconinae, consistingof the genus Falco, Polihierax (pygmy falcons),Spiziapteryx and Microhierax (falconets)and Herpetothe- res (Laughing Falcon); and (3) the genus Micrastur(forest falcons) comprising the third, basal clade. Two genera, Daptriusand Polihierax,are found to be polyphyletic. The phy- logeny inferred from these syringealdata do not support the current division of the family into two subfamilies.
