The 2019 field trip schedule is under development. Below are the field trips scheduled so far.

February 9 (Saturday) at 10 AM: Sourland Mountain Preserve, Somerset County, NJ
The 4,000-acre Sourland Mountain Preserve is situated in central New Jersey's "mountainous" mature forest in the piedmont ecoregion. Set on diabase bedrock, rich upland forest communities here are commonly distinguished by tulip poplar (Liriodendron tulipifera), spicebush (Lindera benzoin), and a speciose herbaceous layer. Undisturbed areas of the preserve host many conservative species including nearly a dozen rare plants. While practicing general winter species identification, this trip will look especially for winter-perennial herbaceous species including virginia pennywort (Obolaria virginica) and crippled cranefly (Tipularia discolor). Hoping to cover two to three miles up through the forested ridge and back down the right-of-way at a relaxed pace, prepare with footwear and otherwise for moderately steep, rocky, and shallow-puddly sections. RSVP to trip leader.
Directions: Meet at the preserve parking lot: 421 East Mountain Road, Hillsborough Township, NJ 08844 (entrance driveway at 40.47504, -74.69268). PDF trail map.
Leader: Gemma Milly, or 609-455-7146 (cell).

April 25 (Thursday) at 1 PM: Haddington Woods, Philadelphia, PA
This site, formerly known as Bocce Woods, has seeps, a former quarry (presently a wetland), and an approximately 100-year-old stand of trees. This woodland is transitioning from an early successional stage with tulip poplar to oak-hickory. There is also floodplain habitat, a wetland that was reconstructed in the late 1990s, and an upland alder stand. It is approximately 23 acres and is part of the Philadelphia Parks and Recreation system. A recent restoration project removed much of the invasive vegetation from the area. Directions: Meet at the parking lot of the Bocce Club at 6525 Vine Street, Philadelphia, PA 19102.
Leader: David Hewitt,

April 26-29 (Friday to Monday): City Nature Challenge, Philadelphia, PA
The Philadelphia Botanical Club is a partner in this 4-day bioblitz to document biodiversity in Philadelphia. You can document plants and/or animals on your own, or you can join outings at various locations in and near Philadelphia. Some of these outings are led by botanical club members. Philadelphia competes against over 100 other cities around the world. In 2018, the winner was San Francisco, with 41,000 observations, 3200 species, and 1532 participants. Can we beat that? See the Philadelphia City Nature Challenge page for basic information and their Events page for a list of outings to join.

August 11-15 (Sunday to Thursday): Joint Field Meeting (BotSoc)
Prairies of Adams County, Ohio

Each year the Botanical Society of America, the Torrey Botanical Society, and the Philadelphia Botanical Club sponsor a field meeting in the area of the northeastern United States. The 2019 meeting will explore Adams County, Ohio and will be housed at Shawnee Lodge & Conference Center. Adams County is located in the beautiful rolling hills of Southern Ohio. It is bounded on the southern side by the Ohio River. Adams County is noted for its fertile farmland, forests, wildlife, prairies and limestone deposits.
Field Trips:
ADAMS LAKE PRAIRIE STATE NATURE PRESERVE: This sparsely vegetated xeric, or dry, prairie is situated on a highly eroded slope of calcareous Estill Shale surrounded by a second-growth oak-hickory woodland. Red cedar, post oak and blackjack oak occur sporadically in the prairie opening. Prairie grasses are sparse, but Adams Lake Prairie supports diverse prairie forbs including a stand of prairie dock. Some of the interesting plants found growing at this cedar barren prairie include spider milkweed, shooting-star, green milkweed, Carolina buckthorn, American aloe, slender blazing-star and large summer bluets. (
CHAPARRAL PRAIRIE STATE NATURE PRESERVE: This is an outstanding xeric limestone prairie with post and blackjack oak. It supports the most extensive population of rattlesnake-master in the state. Prairie dock and spiked blazing-star are also unusually abundant at this site. Eleven state-listed species have been recorded at the preserve, including spider milkweed, prairie false indigo, pink milkwort and American bluehearts. Little bluestem is the dominant prairie grass. (
KA-MA-MA PRAIRIE: The region provides canvas for classic prairie open grasslands, cedar-dominated glades, light-shaded dry bluffs, and young forests composed of oaks, hickories and scrub pines. The grasslands have an unusual number of classic short-grass prairie species such as little bluestem, prairie dock, rattlesnake master, and false gromwell. The extremely rare prairie gentian was found here and is one of only two known locations in the entire state. (
CHALET NIVALE PRESERVE: The dolomite bedrock of Chalet Nivale creates a compelling karst-country landscape of springs, seeps, grottos, and sinkholes. These alkaline soils and bedrocks are renowned for producing a diverse assemblage of rare and endangered wildflowers, ferns and shrubs, including herbs with prairie-associations, such as climbing milkvine, stiff gentian and tall larkspur. Ancient white cedar trees, isolated hundreds of miles south of their normal range in the North Woods, cling to the bluffs of the cliffs. (
E. LUCY BRAUN LYNX PRAIRIE PRESERVE: Designated a National Natural Landmark in 1967, Lynx Prairie was protected to save the best of the few remaining remnants of the once extensive prairies of this area. This preserve features a series of natural grassland openings that appear as islands in an otherwise forested area. These natural openings, called cedar barrens or glades, are prevalent throughout the preserve system. (
DAVIS MEMORIAL STATE NATURE PRESERVE: Geologic features include excellent Silurian dolomite cliffs. Both Greenfield dolomite and Peebles dolomite are exposed. Ohio black shale occurs on the tops of the knobs. An impressive fault, causing vertical displacement of 30 feet, exposes adjacent cliffs of Greenfield and Peebles dolomite. The preserve's dolomite cliffs provide habitat for white cedar and sullivantia. American aloe, dwarf hawthorn, hairy wing-stem, side-oats gramma grass and purple coneflower are found in the prairie openings. Other significant species include tall larkspur, limestone adder's-tongue fern, narrow-leaved bluecurls and Walter's violet. (

dwarf pitch pines (Pinus rigida)
Pygmy pine trees near Warren Grove, New Jersey. These pitch pines are less than 6' tall, thanks to dry, infertile soil and frequent fires. The botanical club visited the site on a field trip in late April, 2017. Photo © 2017 Terry Schmidt.
