ST. JOHN'S UNIVERSITY

The vegetation of Ll.ttle Beach Island, Brigantine National WildlifE:! Refuge,

New Jersey, was extensively studied from May 3, 1989 to November 6, 1989.

Ninety six specific and subspecific taxa of vascular have been identified.

Largest families are the Asteraceae (13 species) and Poaceae (12 species) .

Endangered taxa include Honkenya (Arenaria) peploides Sesuvium maritimum and

Plantago maritima. Major communities on the island include the dune

community dominated by Ammophila breviligulata,. the community

vegetated by Spartina alterniflora, ~. patens, Limonium sp. · Salicornia spp. ,

INTRODUCTION

Little Beach Island, New Jersey, is comprised of approximately 283 ha, is

located in southern New Jersey just north of Atlantic City at 39° 28 N, 74° 34r ~ W. Human habitation of the island during the 20th Century was limited to a fishing

village and Coast Guard Station. The village was abandoned around 1940, the

Coast Guard Station was decommissioned in 1942, and the vegetation was left to its

own devices.

Little Beach Island is among the most pristine coastal islands in maritime New

. Jersey. Since this island has been uninhabited for nearly fifty years, and rarely

visited, it may serve as a bench mark to measure the effect of man's impact on .

barrier islands in southern New Jersey. The present study describes the flora of

Little ·. Beach Island as ··the vegetation of 'this island has .not been previously

described.:- ; .

Coastal storms eroq.e the protective primary dunes and deposit sand on the

inland salt marsh~s, especially on the southern portion of the island. After storm

disturbances, the dunes are rebuilt by natural processes and are colonized and

"stabilizedn by Ammophila breviligulata~ Beach erosion is_espec:ially severe <:>n the

eastern and southern portion the island.

Climate

The nearest weather station to Little Beach Island, is Atlantic City.

January is the coldest month with a mean of O. 4 C while July is the warmest month

averaging 21. 7 C. Rainfall is 1155 mm/yr, and is evenly distributed throughout

the year. November is the driest month with 75.9 mm of rain; August is wettest

month averaging 124 mm. The average length of the growing season is 215 days, 3 Prof. R. Stalter

with the shortest frost free duration being 170 days and the longest duration being

233 days. Hurricanes, northeasters and summer droughts have been recorded

periodically (U.S. D.A. 1977). The most recent storm, Hurricane Gloria,

( September 1985) did extensive damage to the primary dune system especially on

the eastern and southern portion of the island. The large inland dunes

experienced little erosion during Gloria~

Methods

- The vegetation of Little Beach Island was sampled once every three weeks

beginning May 3, 1989, terminating on November 6, 1989. Herbari.um voucher

specimens of each taxon were prepared and deposited at Brigantine National

· Wildlife Refuge.. The species checklist-contains im inventory of the vascular plants_ , 1

of Little Beach Island including native taxa, naturalized and adventive weeds. All

non native species are marked by·an asterisk. The checklist is divided into four

categories: Pteridophyta, Pfuophyta, Magnoliophyta: Magnoliopsida, and

Magnoliophyta: Li.liopsida. Nomenclature follows that of Gleason and Cronquist

(1963) and t_he concept of families follows that of Cronquist (1981).

DISCUSSION

Beach and Swale Cmmnnnity

The vegetation of Little Beach Island can be classified into three general

plant communities: beach and swale community, salt marsh, and immature maritime

forest.

Mari.time Beach and Swale Commmrl.ty

Drift and areas of occasional overwash are present on the northern portion

of the island. . This· area is sparsely vegetated by annual plant species most

_notably Salsola kali, Cakile edentula, Sesuvium maritimum, Atriplex arenariai and

Euphorbia polygonifolia_. Characteristic perennials include Honkenya peploides

' . ssp. robusta and Solid.ago sempervirens. Slightly higher rarely flooded .portions

of the beach are vegetated by the same species and by Ammopb:ila breviligulata·: ,

Panicuin :amarum ·and Solid.ago sempervirens:. -

The ocean and bay bordering dune~ at Little Beach Island are currently undergoing severe erosion. These dunes are currently populated by Ammophila breviligulata., .. · Lechea_ maritima, and Solidago seinpervirens. The sheltered landward side of these dunes is' generally vegetated by th,e same species along with

Toxicodendron radicans,Myrica pensylvanica and Prunus serotina. On sheitered inland dunes in the northeast portion of the island Hudsonia tomentosa,

Andropogon scoparius, Lechia maritima, Polygonella articulata, Toxicodendron radicans, Myrj.ca pensylvanica and Prunus _ serotina thrive. The community supporting Hudsonia is an extremely small conu:µunity covering only a few hectares. 5 Prof. R. Stalter

Maritime Forest Community

The maritime forest at Little Beach Island consists of an almost pure stand

of Purunus serotina, which reaches its best development on the large inland stable

dunes. Prunus serotina, the dominant tree on the secondary dunes at Little Beach

Island, has been recognized as a successional species at Island Beach State Park,

New Jersey (Martin 1959) at Sandy Hook, New Jersey (Stalter 1980) and at Fire

Island, . (Art 1976, Schulte 1965 ~ and Stalter et al 1987). The trees near

the summit of the dunes are generally short and pruned by salt spray; those

occupying the sheltered sides of the dunes where salt spray deposition is minimal

are taller, some as large as 10 meters tall. The dune soils are well drained and

consist of fine sand with a slight accumulation or organic matter. There' are

occasional·individuals of Amelanchier canadensis and Juniperus virginiana~ ·; Ilex ·, '

opaca is extremely: rare; ·.·· only 7 individuals were observed on ·the whole island

during the growing season of 1989.

llex opaca is the dominant ~e at the Bayside Holly Forest, Sandy Hook,

New Jers_ey (Stalter 198 ) and at the Sunken Forest Fire Island New York (Art

1976, Stalte~ et al 1987) . The scarcity of American Holly at Little Beach Island may be due to the young age · of the large stable inland sand dunes as Stalter

(1980) concluded that it might take llex opaca over 100 years to become established on the acreting western portion of Fire Island, New York; hundreds of years passed before _!. opaca became the dominant tree at the Sunken Forest, Fire

Island, New York. 6 Prof. R. Stalter

Salt Marsh Community

The salt marsh community at Little Beach Island occurs along the sheltered

inland portions of the island. The vegetation of the low salt marsh is dominated

by Spartina alterniflora. The higher infrequently flooded salt marsh is populated

by Disticblis spicata, Spartina patens, Salicornia virginica, ~ europaea, Spartina

alterniflora, Plantago maritima, Aster _tenuifolius, and Limonium caroUniannm~ At

the upper marsh boundary, Iva_ frutescens is generally dominant. Baccharis

halimifolia forms the interface between salt marsh and upland vegetation.

- The rarest plants observed at Little .Beach Island are Planta.go maritima

Sesuvi.m maritimum and Honkenya peploides. Their rankings on the 1989 Heritage

Program list, are Sesuvium maritimum - S2 (endangered in the state) Hon.ken.ya -

peploides ·· - S2 ( end · the state) · Plantago · maritinia -.- Sl ( critically

---'--r==;.L...;.. is the -dominant plant in the overwash portions_ Millions of Plantago_mari :tima_occupy the upper infrequently flooded salt marsh in the southwest portion of the island.

The vegetation of Little Beach Island is similar to that. found on other barrier islands in New Jersey especially in the salt marsh and dune communities -

(Martin 1959, Stalter 1981) . Species diversity here is not as- great as that reported by Martin (1959) at Island Beach State Park, N .J., Sandy Hook (Stalter

1980) Cape May Point State Park (Sutton et al 1990) or on Fire Island, New York

(Stalter et al 1987), although there is a greater percentage of natiye taxa here than at the aforementioned areas·. The high percentage. of.native species at Little

Beach Island is probably the result of its isolation with respect to ma.n's activities. Table 1. A statistical summary of the vascular flora of Little Beach Island, New Jersey
