Unmanned Aerial Systems and Burn Management Strategies

On September 19, 2019 a controlled burn was conducted on the Doak grassland and forest property, owned and managed by the Department of Forestry and Natural Resources at Purdue University. Burn events such as this one present a unique opportunity to demonstrate how UAS can be utilized as an effective tool to both monitor the burn events in real time, but also to effectively gather data before and after the burn to map and better manage vegetation. This collection of maps, videos, and images provide a narrative on how UAS can be used as an effective tool in controlled burn management practices. Beyond controlled burns, the story should demonstrate how UAS can be used to better monitor and inventory other disturbance events, whether they are planned or unexpected.

A Collaborative Effort
The data collected for this event represents a collaborative effort between multiple colleges at Purdue University and private industry. Employees with Purdue Forestry and Natural Resources (College of Agriculture) performed and managed the burn while data collection for the pre and post-burn mapping was conducted by student researchers and pilots from the Purdue School of Aviation and Transportation Technology (SATT; Polytechnic Institute). Peter Menet and Chris Johnson from MenetAero provided aerial monitoring support throughout the controlled burn. A total of three different aircraft were used during this event. The SATT student pilots deployed a C-Astral Bramor PPX equipped with a MicaSense Altum 6 band multispectral sensor at 121 meters before and after the event for mapping purposes. MenetAero deployed a C-Astral C4Eye to monitor the burn in real time using EO/Thermal IR video with real time geographic coordinates at 121 meters while SATT students monitored the burn with a DJI M600 equipped with a Zenmuse XT2 sensor at lower altitudes.

Monitoring the Burn:
The nimble nature of UAS makes them ideally suited to deploy rapidly, and into tight situations otherwise too dangerous for ground crews and manned aircraft. Add to this the aerial perspective offered by UAS via real-time video feed, and you have the perfect platform to assist in hazard events such as fire. The real-time video feed allows the UAS pilot and crew to communicate with ground-based fire crews, providing information on potential hazards and overall fire behavior patterns. For this aerial perspective to be effective, however, the video needs to have geospatial context so what the UAS operator is seeing is effectively communicated to ground-based fire crews. Full-Motion-Video, or video that has metadata with geospatial coordinate information, is a game changer in this regard. The video below shows how software such as Remote Geosystems Line Vision Ultimate can place video in a geospatial context. The video below is being played after the flight, but Pete Menet from MenetAero had the video live streaming to his Ground Station during the flight and was able to effectively serve as an ‘eye in the sky’ to provide real time information to ground based crews. This was all done in a controlled burn, but this same technology and method is used by MenetAero during Wild Fire Events where MenetAero provides UAS services as a contractor with the U.S. Department of Interior. Peter Menet and the MenetAero crew were kind enough to donate their services and time to the controlled burn event this day as part of a collaborative research effort between industry and Purdue.

A Before and After Comparison
Prior to recent advances in UAS technology, gathering imagery at sub-centimeter accuracy and resolution immediately before and after a planned burn event would prove difficult at best. The PPK technology on the C-Astral PPX allowed us to conduct the flights without the need to layout and survey ground control markers, but still achieve centimeter level accuracy by post-processing our data with a Continuously Operating Reference Stations in close proximity. Without UAS, getting satellite data within this time frame would have been pretty much impossible, and getting a manned aircraft to do this prohibitively expensive.

Making Sense of it all through Classification Analysis
Pre-Burn Land Cover Classification
When we think of disturbance events, we often think of the unplanned ones – fire, ice storms, wind storms, floods, etc. But what about planed disturbances such as a controlled burn, or a timber harvest operation? In the case of a planned disturbance, we have the ability to inventory land cover immediately before an event, and then with classification methods, quantify that land cover. Land Use/Cover classification methods are nothing new, and go back to the very beginnings of GIS/Remote Sensing, but new here is the ability to deploy a UAS to get this data in a way that is accurate and precise enough to classify down to resolutions of several square centimeters. Add to that the imagery was gathered less than an hour before the burn and you have some amazing potential for forestland management.

Cities and towns in the U.S. contain more than 130 million acres of forests. These forests vary extensively in size and locale. An urban forest can describe an urban park such as Central Park in New York City, NY, street trees, nature preserves, extensive gardens, or any trees collectively growing within a suburb, city, or town. Urban forestry is the name given to the care and maintenance of those ecosystem areas that remain after urbanization. Data from the 2010 census indicated more than 80% of Americans live in urban centers with a population increase greater than 12%. The population of Indiana represents only 2.1% of the nation. In the last 8 years, IN has had an influx of 200,000 people which represents a population increase of 3.0%!

Urban forests, which help filter air and water, control storm water runoff, help conserve energy and provide shade and animal habitat must be maintained. As our nation becomes more urbanized, appreciate those urban foresters working to ensure we have save urban forest spaces to enjoy. These precious resources add more than curb appeal and economic value, they improve our quality of life.

This past summer marked the first year of the Research and Extension Experiential Learning for Undergraduates (REEU) program at Purdue University. This program entitled “Diversity in Faces, Spaces and Places” was designed to increase visibility of underrepresented students and professionals in Natural Resource sciences disciplines and provide targeted mentorship to current underrepresented undergraduates.

During this PAID 8-week summer program, students were exposed to and participated in a plethora of activities such as: stream ecosystem health evaluation, mammalian tracking and trapping, reptile and amphibian habitat suitability studies, avian mist-netting, bat auditory identification and examination, and the role of genetics in the susceptibility of trees to disease. Students created posters of their research, gave oral presentations, and wrote a manuscript article on their chosen topic of study at the end of the program. Be a part of the fun next year!

Northern strain largemouth bass, photo by Mitchell ZischkeFish stocking in a pond is like a retirement plan—you need to have a vision of your ultimate goal. You want to start off in the right direction or your long-term investment may not pay the dividends you had hoped for. Pond Management: Stocking Fish in Indiana Ponds is an 8-page publication written by our experts partnering together from Purdue’s Pesticide Programs, Forestry and Natural Resources and Purdue Weed Science. They share recommendations regarding fish types, numbers, and predator/prey relationships for new and renovated ponds.

Main topics include:

  • Stocking new or renovated ponds with no fish present
  • Assessment of ponds with existing fish populations
  • Northern strain largemouth bass
  • Stocking fathead minnows
  • Stocking fish to control vegetation
  • Dissolved oxygen – fish need it to live
  • Fish health

Properly stocking your pond with the correct number of the recommended species at the right size are all important steps in creating a healthy and well-balanced pond that will provide good fishing into the future. For more information on pond management go to extension.purdue.edu/pondwildlife or contact Dr. Mitchell Zischke at mzischke@purdue.edu.

Storm damage, trees downSafety first! Stay clear and look for dangerous hanging limbs, broken branches and other failures before beginning cleanup or inspections. Keep others clear of the areas beneath and around damaged trees. Be alert for power lines that could be involved with damaged trees. All utility lines should be considered energized and dangerous.

Lindsey Purcell, Purdue urban forestry specialist, shares, “in my experience, during storm cleanup, many tree owners are faced with the decision of what to do with their trees relative to restoration or removal”.  There are several types of tree damage that occur from violent weather. Each has its own specific assessment considerations. All parts of the tree should be inspected during a post-storm assessment. This requires the expertise of trained, professional arborists to assist with the decision making regarding the best course of action. Unfortunately, there are those who take advantage of the situation and overcharge or provide poor advice when it comes to the best decision on their trees. Don’t make any hasty decisions and be sure you are hiring an International Society of Arboriculture (ISA) Certified Arborist, ask for references and proof of insurance in the process.

When encountering turtles, it is important to leave them alone to ensure their safety in their natural habitat. Several of Indiana’s turtle species are illegal to takeEastern box turtle or possess, including the Eastern box turtle (pictured right). Unless a turtle needs assistance crossing a road, it should never be picked up or moved.

What should be kept in mind if you encounter a turtle who may need help?

People often encounter nesting females on roads during May and June. If a female is taken out of the wild, she can no longer add to the population.

Turtles are long-lived species and have significant care requirements. Captive turtles cannot be released into the wild. They can introduce diseases or parasites to the wild population, and they will likely not survive.

You can help turtles cross the road. Always move the turtle across the direction that it was heading.

Any turtle collected from the wild requires either a legal license or permit and all reptile eggs and endangered species or species of special concern are protected.

View the resources below on reptiles and amphibians along with Indiana’s regulations answering any questions you may have for collection, handling and conservation efforts.
