Dell Avenue Rock consists primarily of a puddingstone ledge arising approximately 40 feet above Hyde Park Avenue. There are some outcrops near the top of the rock. The site is dominated by woodland, comprised of small and medium sized maples, oaks, cherry, and birch with sparse, grassy ground cover. This site provides a pleasant visual buffer along a busy, dense stretch of Hyde Park Avenue. Views from the top of the rock overlook the Stony Brook Reservation and in the winter there are views of the Blue Hills. The open, grassy areas on the lower portion of the site provide a quiet retreat for picnics or reading.

As Boston's second largest wooded area, Allandale Woods is a crucial component of the city's natural areas inventory. Allandale Woods is located behind the Arnold Arboretum on the Jamaica Plain/West Roxbury line and is bordered roughly by Allandale Street, Centre Street, the VFW Parkway, and Hackensack Road. The acquisition of conservation land at Allandale Woods in 1975 represented the first step in creating the Charles-to-Charles open space corridor, an 8-mile open space belt of existing parkland, private estates, and wetlands that stretches from the Fens and the Charles River Basin, along the Boston/Brookline boundary, and through the Sawmill marshes to the Charles River in West Roxbury. Composed primarily of oaks, maples, and pines, Allandale Woods is one of the few relatively pristine secondary growth oak-hickory forests in the city of Boston. Trails, laid out by the Appalachian Mountain Club in 1992, run throughout the site leading to various areas fo interest including three ponds, several streams, and a marsh.

Back of the Hill Urban Wild is composed of a steep forested slope stretching from Huntington Avenue to Parker Hill Avenue. The only approaches to the wild are from the back of the elderly facility off Huntington Avenue and the end of Colburn Street, a private road owned by NSTAR Electric. NSTAR Electric also owns an adjacent portion of the hill located north of the city-owned conservation land. For years, NSTAR has debated the construction of a transmission station at the base of their land. The southern section of the wild abutting the elderly facility hosts a field of grasses and hedges. Earthworks Projects has strategically planted the lower section of this grassy area in order to prevent erosion near the elderly facility.

Belle Isle Marsh Reservation preserves 152 acres of the 241- acre Belle Isle Marsh, Boston's last remaining salt marsh. The Belle Isle site is located on the west side of Belle Isle Inlet, just north of Logan International Airport and across the inlet from Winthrop. In addition to the preservation of the natural areas of the marsh, the Division of Urban Parks and Recreation manages 28 acres of landscaped park with pathways, benches and an observation tower. Guided walks explain the natural and cultural history of Belle Isle. Topics covered include saltmarsh ecology and the history of man's use of and the impact on the marsh. Special programs for community and school groups can also be arranged by contacting the reservation. Part of the Boston Harborwalk, a pedestrian path meant to revitalize and improve the enjoyment of Boston waterfront and promote its access to the public.

Boston Natural Areas Network (BNAN), organized in 1977, works to preserve, expand and improve urban open space through community organizing, acquisition, ownership, programming, development and management of special kinds of urban land.

This urban sanctuary, located on the grounds of the former Boston State Hospital, offers public programs year-round. Through its Boston Schools Initiative, the Boston Nature Center provides environmental education programs to Boston elementary schools weekly. Two miles of wheelchair accessible trails and boardwalks traverse meadows and wetlands where wildlife abounds, including coyotes, pheasants, and many species of migratory birds. The sanctuary’s George Robert White Environmental Conservation Center is one of the “greenest” buildings in Boston, teaching environmentally sustainable design by example. The site also includes the Clark-Cooper Community Gardens, Boston’s oldest and largest, providing food and a green oasis for 260 local families. On site, the Clark-Cooper Community Gardens, Boston's largest community gardens, provide food and a green oasis for hundreds of Boston residents. The Boston Nature Center offers programs for adults, youth, and families throughout the year to foster an appreciation for the urban environment and to support life-long learning. Check the calendar for upcoming programs. Space is limited, so pre-registration and pre-payment for all programs is encouraged. Be sure to dress appropriately for the weather. Tip: It's easier for everyone if infants brought to family programs come in backpacks rather than strollers.

Tucked between the Forest Hills Station and the Arnold Arboretum, the Bussey Brook Urban Wild, also called the South Street tract, has recently been incorporated into the arboretum. As part of the annexation, a stabilized stonedust pathway was constructed through the wild from Forest Hills Station to South Street. Select areas were cleared of prior vegetation and replanted. However, the majority of the site remains in its former condition. Boasting a small section of the Stony Brook, this is the last area where the brook can be seen before it is funneled into the conduit to the lower basin of the Charles River. As a low-lying area, the wild is composted of a marsh and upraised filled land.

This small wetland and forested upland area is sandwiched between the playing field of a local elementary school and a housing development along Hilburn and Seymour Streets. As a result of these adjacent development projects, a considerable amount of the wetland has been subject to fill and dumping. A fence currently surrounds the site preventing access. The upland portion of the site contains the foundations of a building that once perched above the wetland. As a functioning wetland, this area provides flood storage, water filtration, and wildlife habitat. Although the area is highly degraded and overrun with invasives, native wetland plants, such as cattails, and a decent canopy of oaks, red maple, and elm do persist. Birds extensively utilize the site for nesting and feeding purposes. However, in its present, fenced condition, the wetland provides little benefit to the neighboring community.

The Cedar Street Urban Wild is surrounded by residential housing on two sides and by community gardens on two sides. A pathway winds through the wild linking the Allan Crite Garden on Cedar Street to the Highland Center Garden on Linwood Street. Both gardens are managed by the Boston Natural Areas Network. A gate provides direct access to the urban wild from the abutting residential development. The wild can also be accessed from either community garden. A portion of the urban wild has been cultivated with perennial flowers and fruiting trees including hazelnut and apple. The most notable of feature of the urban wild is a large puddingstone outcrop located in the western portion of the property. Invasive sycamore maple and Norway maple dominate the site creating a shade so dense that little other than garlic mustard and mugwort survive in the understory. As a result, groundcover is sparse. A few pine oaks have survived near the rock outcrop.

This is a fan-shape parcel of inter-tidal land at the intersection of Border Street and Condor Street, between the Mobil Station and the Shore Plaza apartments. Though it is underwater for significant periods and there is no direct access, this site provides sweeping views of the inner harbor, looking toward the Tobin Bridge and Mystic River. If privately owned, buildings would have been constructed here blocking the view, as has occurred on the adjacent parcels. Inter-tidal habitat is widely regarded as an extremely valuable natural resource. These areas are home to many species of shellfish, other invertebrates, and juvenile fish. They also play important roles in flood control and water quality improvement.
