Bosque del Apache National Wildlife Refuge

Template:Short description Template:Use dmy dates Template:Infobox protected area

The Bosque del Apache National Wildlife Refuge (Template:IPAc-en Template:Respell, {{#invoke:IPA|main}}; "Woodland of the Apache") is a National Wildlife Refuge located in southern New Mexico. It was founded in 1939 and is administered by the U.S. Fish and Wildlife Service. It is a favorite spot to observe sandhill cranes, which spend the fall and winter in the area. The reserve is open year-round and provides safe harbor for its varied wildlife.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Visitors to the refuge also enjoy partaking in activities such as hiking, cycling, driving tours on the 12-mile scenic auto route, and participating in educational programs offered on site.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

LocationEdit

The name of the refuge means "woodland of the Apache" [[[:Template:Abbr]]] in Spanish, named for the Apache tribes that once camped in the forests along the Rio Grande.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Previously, the Piro people had lived in the lands around what is now the refuge until the 1600s, when they were forced to abandon their pueblos due to European diseases and attacks from the Apache tribes.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The heart of the refuge comprises approximately Template:Convert of Rio Grande floodplain and Template:Convert of irrigated farms and wetlands. In addition to this, the refuge contains Template:Convert of arid grasslands and foothills of the Chupadera and San Pascual Mountains.<ref name="bosque_about"/> The refuge sits within the Little San Pascual Mountain fault zone, rendering it an ideal site for conducting research on stratigraphy and sedimentology.<ref>Template:Cite journal</ref>

About Template:Convert of this is designated as wilderness.<ref name=":0" /> A twelve-mile-long (19 km) loop road divided by a cutoff into a "Farm Loop" and "Marsh Loop" allows automobile drivers excellent views of wetland wildlife and raptors, and there are several short (1.5 to 10 miles) walking trails.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The road affords good views of the fields where crops are grown for the benefit of the birds under cooperative agreements with farmers. Adjacent to the Visitor's Center, a desert plant garden is maintained.<ref name="bosque_map" />

About 7,000 acres (28 km²) in the center of the refuge are made up of flood-plains watered by irrigation systems connected to the Rio Grande. These flood-plains provide an essential habitat for cottonwood and honey mesquite trees, Goodding's and coyote willows, and four-wing saltbushes. The plains are flooded periodically to give these plants the best growing conditions.<ref>Template:Cite book</ref> In recent years, elk have caused damage to corn crops at the refuge. This damage disrupts the refuge's capacity to supply supplemental food to the sandhill cranes and other waterfowl species that overwinter there.<ref>Template:Cite journal</ref>

The flood plains also grow foods for the wildlife that need marshlands to grow. These plants include smartweed, millet, bulrush, chufa, and various sedges. These marshlands begin dry, and are burned or turned over before they are flooded in order to produce fresh soil for the new plants. They are then flooded to become the breeding grounds for these marsh plants.<ref name=":0" /> The Bosque del Apache National Wildlife Refuge and the wetlands near the Elephant Butte and Caballo reservoirs demonstrate considerable promise for sustaining breeding bird populations over the course of the century. Similar suitable breeding terrain is found only on private land surrounding the refuge.<ref>Template:Cite journal</ref> Changes in surface flooding and vegetation structure are not affecting shrub-nesting birds who can use other woody debris for nesting; however, canopy nesting birds rely on native trees and are thus more sensitive to environmental changes.<ref>Template:Cite journal</ref>

The Bosque del Apache is also made up of several acres of dry land. One unit contains 5,440 acres (23 km²) of scrubland and desert terrain that is connected to the Chihuahuan desert. This area is called the Chupadera Peak Wilderness Unit. In addition to desert terrain, the Chupadera Peak Wilderness Unit is characterized by tall, reddish cliffs.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

BirdsEdit

There have been 393 different bird species observed in the Bosque del Apache National Wildlife Refuge since 1964 according to eBird, making it one of the most diverse areas for bird species in the United States .<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The wetlands attract the huge flocks of wintering cranes and geese that are the refuge's most interesting feature. Many other species—notably waterfowl, shorebirds, and birds of prey—also winter in the refuge. Striking vagrants such as a groove-billed ani and rufous-necked wood rail have been found there. In the Chihuahuan desert terrain outside of the Rio Grande riparian zone, the refuge also hosts three federally designated Wilderness areas (Chupadera, Little San Pascual, and Indian Well).

The diversity of birds is also high in spring, particularly the last week of April and first week of May, and in fall. In summer the area is hot but many water birds can be found, including such New Mexico rarities as the least bittern and occasionally the little blue heron. Late November to late February is the best time for large numbers of birds, typically over 10,000 sandhill cranes and over 20,000 Ross's and snow geese. An annual 'festival of the cranes' is held in early December as large numbers of cranes begin arriving in the refuge. Winter visitors generally plan to be in the refuge at sunrise or sunset, when the flocks of cranes and geese that roost in the refuge "commute" to or from local fields where they feed. Although winter sunsets and especially sunrises are chilly, the daily low temperature is seldom far below freezing. Visitors typically stay in the nearby RV park or in Socorro or San Antonio.

BiologyEdit

In addition to hosting rare bird species, Bosque del Apache National Wildlife Refuge is also home to the southernmost known population of the New Mexico meadow jumping mouse along the Rio Grande river. This mouse is a distinctive, genetically unique subspecies found in certain regions of New Mexico, Arizona, and southern Colorado. Due to its rarity, the New Mexico meadow jumping mouse has been listed as an endangered species under the U.S. Endangered Species Act.<ref>Template:Cite journal</ref>

An overabundance of the invasive tree species Tamarisk (also known as salt cedar) on the refuge has posed a threat to habitats utilized by native wildlife species. To combat this issue, Bosque NWR has utilized various control methods over time, such as mechanical removal, herbicide application, and prescribed burning. The Tamarisk removal efforts undertaken on the refuge have served as a case study for similar removal initiatives in other protected areas.<ref>Template:Cite book</ref>
