Rebirth After Fire

Located within Minnewaska State Park Preserve is Sam’s Point, an area of unique ecological significance encompassing roughly 5,000 acres in the Shawangunk Mountains of southern New York. Toward the end of April, during a particularly dry and windy week, a fire broke out along the Verkeerderkill Falls Trail and engulfed over 2,000 acres of pitch pine and oak woodlands. While this may seem like a devastating event, one of the factors that make the globally rare dwarf pine ridge ecological community of Sam’s Point so unique is that it is a fire dependent ecosystem.

Since progressing into the deep summer months, Sam’s Point has experienced an explosion of new growth. Toward the end of the fire there was an extended period of cold rainy weather that continued for a week after the fire was out. Soon afterward , bracken fern (Pteridium aquilinum) fiddleheads began springing forth through the burned earth and painted trilliums (Trillium undulatum) flowered near the Ice Caves trail in an area of low intensity burn. A number of pink lady slippers (Cypripedium acaule)  also popped up along the Loop Road and the Verkeerderkill Falls Trail.

Sam’s Point was fully closed until Memorial Day Weekend, when it was reopened to limited capacity with only the Loop Road and Ice Caves Trail available to the public. Park staff members were positioned at the Verkeerderkill Falls Trail with a table of educational materials in order to encourage park patrons to obey the closures and help them understand the importance of staying out of affected areas. The main concern is the potential for rapid spread of non-native invasive plant species by seeds hitchhiking in the boots and backpacks of visitors. Without competition from established plants and with the increased availability of nutrients that follows fire, invasive species have the potential to quickly establish.

Fortunately, the closures seem to be working and few invasive plants and many native species have been seen in those areas. Blueberries (Vaccinium spp.) and huckleberries (Gaylussacia baccata) have been quick to return, along with chokeberries (Photinia melanocarpa), serviceberry (Amelanchier sp.), wild raisin (Viburnum nudum) and sheep laurel (Kalmia angustifolia), which have repopulated the understory in a carpet of vibrant green. Rhodora (Rhododendron canadense), a small, showy rhododendron that is threatened in New York State, has been proliferating in high numbers in some of the wetter areas of Sam’s Point. Even bunchberry (Cornus canadensis), a wildflower more typical of cool, moist woodlands and uncommon in southern New York, is coming back near the Indian Rock Trail.

Many of the pitch pine trees that were blackened and scorched, all of which looked ostensibly dead, have exhibited new growth occurring at the base, epicormically (along the trunk), and from the top of the tree. Walking along the loop road, hints of long bristly shoots resembling bright green porcupines are apparent on a number of blackened trees. The majority of pitch pine stumps that were cut for fire control purposes have also begun re-sprouting.

New Shoots on Pitch Pine
Pitch pine is not the only tree sending out new shoots—scrub oaks, birches, red maples, and aspens are also exhibiting basal sprouting on burned trees.

Equally important for the ecology and continuance of the globally rare dwarf pine ridge community  is the successful germination of pine seeds. As pitch pines get older, they lose their ability to re-sprout. Many older pitch pines will experience a wave of mortality even after new shoots appear. Possible reasons for this subsequent mortality of pitch pines is that a burned tree tends to be more stressed, and may not as resilient to any new factors that can further increase stress, such as insect predation and extreme weather events. Additionally, new shoots probably won’t distribute evenly on each tree, and this added weight on a weakened tree can cause branches to break or the entire tree to topple over. But there is still hope. The closed, charred pine cones opened soon after the fire ended, their russet innards contrasting brightly against the blackened landscape. The seeds were dispersed and fell to the ground. In order to germinate, pitch pine seeds need to be exposed to mineral soil. This is usually achieved when a fire burns through the upper duff (dead leaves and other plant material) and organic soil layers, which are more likely to burn when the fire is allowed to continue for long enough and reach a hot enough temperature. Until recently, the park staff at Sam’s Point had been unable to find any seedlings despite nearly half of the acreage on Sam’s Point being burned.

But how do you monitor 2000 acres for seedlings? You don’t. Instead, you look at a sample. One of the first post-fire initiatives by Parks’ Sam’s Point research staff was to establish 20 randomly placed research plots in order to document forest regeneration and the recovery of this natural area over time. Returning to the plots and recording information on the plants and soil helps us to understand and learn more about this ecosystem. In addition, we established photopoints in four of the research plots. Since May 7th, we have been photographing four plots from the same location on a biweekly basis. Photopoints are a great supplement to research documenting change over time, as it provides a way to visually understand what changes are taking place.

Sampling is scheduled to begin sometime in August, but one of the most exciting aspects of establishing randomly placed plots is discovering unique areas that might otherwise go unnoticed. During our fieldwork we found several areas of pitch pines averaging only 4 feet tall. Upon further examination, we discovered that the soil was extremely shallow in those spots, as little as 2 inches over solid bedrock. In July, none of Sam’s Point staff had seen any new seedlings during their regular duties around the park, but after checking in on the sections with low soil depth we were able to find a good number of seedlings. And soon after, seedlings were found in some of the wetland pockets as well. All good news for the recovery.

Sam’s Point has a number of unique, highly acidic wetlands too. While the larger pockets were relatively untouched by the fire, the smaller outflows were more vulnerable, especially in areas of extremely shallow soil. However, the wet areas that were burned along High Point Carriage Road and some other narrow strips of wetland have begun exhibiting their wetland qualities once again. Sphagnum moss, a characteristic moss genus found in bogs, has returned in some of these areas, while tiny sundews (Drosera spp.) can be seen on both the newly grown moss and the saturated but still blackened soil.

Animal activity was apparent almost immediately. The prairie warblers’ ascending trill could be heard throughout the spring in all areas of the preserve. Insect and pollinator activity has been high, especially with the return and subsequent blooms of milkweeds and meadowsweet. Park staff also noticed a number of ruffed grouse, which like forest openings. The remains of chewed up pine cones littering the forest floor are evidence of red squirrels. Eastern towhee activity was also high in the period immediately after the fire. Towhees are a species of bird that feed on pitch pine seeds as they are released from their cones. Amphibians could be spotted burrowing into the moist ground in order to keep cool.

During a fire and the initial period afterward, it is easy to focus on the destruction and negative impacts. However, it’s important to remember that fire is a vital ecological process in many environments, especially for the health and longevity of pine barren communities. The Sam’s Point Fire offers great opportunities for discovery. Researchers from the Shawangunk Ridge Biodiversity Partnership, Mohonk Preserve, The Nature Conservancy and nearby colleges like SUNY New Paltz met to discuss research needs and interests to inform management and increase our knowledge about this exceptional place and ecosystem. It’s exciting to see what the future holds for Sam’s Point.

Magnificent Moths

It’s National Moth Week! So let’s learn a little more about them.

Moth or butterfly?

Moths and butterflies are members of the order Lepidoptera (Greek for scale and wing). Most butterflies have club-shaped antennae – a thin stem with a ball at the end – whereas moths usually (but not always) have feathery antennae like the luna moth above. Moths often have fuzzy, short bodies compared to the more slender, smoother body of butterflies.

Are all moths small and brown?

Many moths are small and brown, tan or white. But many are much fancier; in fact you may have mistaken some colorful ones for butterflies. Sometimes the colors are hidden while the moth is at rest, but revealed when in flight, like the tiger moth. The silk moths are spectacular in size and color – such as the Luna moth above.

How many different kinds of moths are in NY State?

There are over 1,000 moth species in the state. A single State Park can harbor dozens to hundreds of different species of moths. Larger parks and those with rare habitats are great examples of places that support a diversity of different species of moths. To date, scientists have identified about 90 species in Watkins Glen and Taughannock State Parks, over 300 species in Minnewaska State Park Preserve, and nearly 500 species of moths each at Hither Hills and Napeague State Parks!

Where and how do you find moths?

Most moths fly at night. The easiest place to see moths is at a porch light or around the lights of campground buildings. For better viewing hang a sheet or light colored cloth up with a light next to it. The moths will land on the sheet (see below) so you can get a close up look without even touching them. Other moths prefer daytime or can be seen resting during the day.

Why are those moths in boxes?

A lot of moths are difficult to identify. So scientists collect and preserve specimens in order to look at them closely to identify them. Collections are also important as a permanent record of what species were found at a site. Each specimen is labeled with location, date, and species name. Then the specimens are placed in ‘safe storage’ in a museum such as the New York State Museum or a university collection where they can be used for other research or study.

Are there rare moths in State Parks?

Yes!  For example, four rare moth species have been found in Minnewaska State Park Preserve and over 30 rare moth species have been documented in Napeague and Hither Hills State Parks on Long Island. Some have fun names like fawn brown dart (Euxoa pleuritica), pink star moth (Derrima stellate), chocolate renia (Renia nemorali) and black-bordered lemon moth (Marimatha nigrofimbria). Most areas of the state have not even been surveyed for moths, so there is much more to learn. Currently, over 100 species of moths have been identified as rare in the state. See the NYNHP Rare animal list  for the listing of New York’s rare moths.

Quiz answer: The woolly bear caterpillar (Pyrrharctia isabella) becomes the Isabella tiger moth (Pyrrharctia isabella). Moths are one of the few groups that have different names for different life stages of the same animal. This is one reason why scientific names are important; from the common names we might think this caterpillar and moth were not related.

New York State Invasive Species Awareness Week 2016

This week marks New York Invasive Species Awareness week!

July 10th – 16th, 2016 the State of New York is celebrating their third annual Invasive Species Awareness Week (ISAW). The purpose of this week is to bring awareness to the public regarding the harmful effects of invasive species around our state. Invasive species are non-native species that inhabit a new environment, causing harm to that new environment. Not all non-native species are considered invasive. In order to classify a species as invasive, it can cause ecological, social, human health, and or economic damage. Invasive species often spread unintentionally through human activity. The trade of goods around the world is one of the primary sources of invasive species transfer. Cargo ships for instance can carry aquatic invasive species in their ballast tanks or insects in their shipping containers. Once established in these new environments invasive species can spread quickly because these ecosystems often have no natural predators or control. The presence of these hitchhikers is one of the leading threats to our native species and ecosystems. By out-competing, preying upon native species or carrying disease, invasive species can be detrimental to native species and the biodiversity of natural habitats.

Invasive species come from near and far and affect all types of habitats found throughout New York State. Since many of our commercial, agricultural, and recreational activities are dependent on a healthy native ecosystem the presence of invasive species can impact all people and the natural world. Aquatic invasive species such as hydrilla (Hydrilla verticillata), water chestnut (Trapa natans) or zebra mussels (Dreissena polymorpha) have inhabited many of New York’s water ways. On land, species such as Japanese knotweed (Fallopia japonica), can overcrowd native environments.

How you can help!

Boaters/Anglers Wash and dry your boat properly. Be sure to remove all plant matter from boat, ballast, prop, trailer and all equipment. Dispose debris correctly. Use aquatic invasive species disposal station if available.

Campers/Hikers/Bikers Check clothing, boots, pets, and camping gear for seeds, plant matter and insects. Clean gear and dispose of debris properly. Use local firewood.

Gardeners Plant only native plants. Educate yourself and others about the importance of using native species. There are many native look-alikes that are just as beautiful.

Whether you are a boater, fisherman, hiker, gardener or simply a concerned citizen, it is important to educate yourself and others on the different species found in your home state. You can make a difference in stopping the spread of invasives! Here you can find information on invasive species found in the State of New York.

Many State Parks have events during New York Invasive Species Awareness Week to involve the public in preventing the spread of invasive species.

Learn more by contacting your local PRISM! Partnership for Regional Invasive Species Management for more information on Invasive Species.

Southern Pine Beetle in New York

Southern pine beetle has killed thousands of pine trees since it was first found in New York State in 2014. This bark beetle is native to the southern United States, but arrived in New York after working its way northward for many years. Although the beetles are small (2-4 mm; less than 1/8th inch), they are able to kill trees in 2 to 4 months by attacking in large numbers. Once beneath the bark, the thousands of beetles create S-shaped tunnels as they feed on the inner bark, which soon cuts off the nutrients the tree needs to survive and grow.

In New York, pitch pine trees have been attacked by southern pine beetle more than any other species. Pitch pine trees are often a part of unique, globally and statewide rare ecosystems such as Pitch Pine-Scrub Oak Barrens, Pitch pine-oak heath woodlands, Pitch pine-heath barrens, Pitch pine-oak-heath rocky summits, Dwarf pine plains, and Dwarf pine ridges. In New York, southern pine beetle has been found in trees across Long Island and in traps as far north as Minnewaska State Park Preserve in the Shawangunk Ridge. Large forested and unique areas such as the Long Island Central Pine Barrens Preserve and the Shawangunk Ridge are of the highest priority to protect. Maps of the pitch pine communities of statewide significance created by NY Natural Heritage Program provide further guidance on priorities. Although there are no known means to eradicate southern pine beetle, there are measures to reduce the beetles’ impacts and save some of the susceptible pines.

To help fight against southern pine beetle, the NY State Department of Environmental Conservation’s (DEC) Forest Health team has conducted trapping, aerial surveys, and ground surveys to monitor for the beetle and cut infested trees (suppression) to manage the beetle. Currently, suppression efforts are focused in the Central Pine Barrens of Long Island. In some cases, pines are replanted along trails or in areas where impacts have been high. The beetles do not attack small, young trees, so the hope is that some trees will survive and produce seed to maintain pine in these ecosystems.

In areas that the beetles were captured in traps, but were not found in trees, such as at Bear Mountain and Minnewaska State Parks, the focus continues to be on early detection and surveying for infested trees. DEC conducts aerial surveys over Bear Mountain and Minnewaska State Parks to map out areas potentially infested with the beetle. These aerial surveys are quickly followed up by ground surveys by DEC, State Parks, NYNJ Trail Conference, and others to verify if the trees are infested. So far, no ground surveys have found infested trees in either of these parks.

Efforts at Connetquot River State Park Preserve on Long Island, one of the hardest-hit areas, are focused on removal of dead trees. State Parks, with help from the Excelsior Conservation Corps (an AmeriCorps program) has been cutting down dead trees killed by southern pine beetle along trails to keep the trails safe and open to visitors. State Parks is also chipping up some of these dead trees to help speed up decomposition.

DEC, Parks and Trails New York, and State Parks co-sponsored tree planting as part of I Love My Park Day in Connetquot River State Park Preserve on May 7th, 2016. DEC’s Tree for Tributaries trained volunteers to plant the 600 pitch pine that were donated from New York State’s Saratoga Tree Nursery. The pitch pine trees were raised from seed originating from Long Island and will help maintain the local pitch pine genetics that is adapted to the conditions of Long Island. Through hazard tree mitigation, chipping, suppression, and re-planting pine trees in areas attacked by southern pine beetle such as Connetquot, hopes are that forests will remain safe for public use and maintain their pitch pine components in the wake of southern pine beetle.

Wildfires are nature’s way of thinning the pitch pine forests and woodlands and keeping these ecosystems healthy. Without fire the pines get too dense and are more susceptible to pests like the southern pine beetle. Mechanical thinning (cutting) can mimic some of the ecological processes of fire to benefit the communities of rare species and reduce SPB infestations. Photo credit: J. Lundgren, NYNHP.
