Many of our favorite plants have multiple personalities. There is a good side and a bad side, shown especially when they escape the landscape and spread to our native areas, becoming invasive. When it comes to invasive plants in landscapes, there is good news and bad news. The bad news is that invasive plants are planted intentionally as ornamentals, and several species known to be invasive are readily available for sale from nurseries and garden centers. The good news is that there are many beautiful plants to choose from that are not invasive. Indeed, while many of the most picturesque garden plants are not native to the Midwest, the majority are not invasive. For example, hosta, smoke tree, boxwoods, Japanese tree lilacs, dwarf shrub junipers, and serviceberry are all non-native to the region but are not known to be invasive. However, brad ford pear, red barberry, burning bush and other “go-to” landscape plants are damaging our natural ecosystem by establishing themselves where they really aren’t welcome. These plants should be avoided and even considered for removal and replacement.

Several professional landscape and nursery organizations have taken the charge in eliminating these harmful plants. They believe invasive species adversely affect the integrity of ecosystems and cause both environmental degradation and economic harm. Invasive species – whether they are plants, animals, fungi, or insects – may cause deterioration of native habitats and plant communities as well as damage to designed and managed ecosystems. Because invasives reduce biodiversity and disrupt the healthy structure and function of both native and human ecosystems, planners, contractors, arborists, landscape architects and other green industry professionals should not introduce or support the use of known invasive species. And, where they are already existing, steps should be taken to eradicate them.

Invasive species are any plant, animal, insect or plant disease not native to a specific location that can cause harm to the environment, impact the diversity of native species, reduce wildlife habitat or disrupt important ecosystem functions.

As spring approaches, many invasive plants are beginning to leaf out in local woodland areas. Now is the time to stop them in their tracks so they don’t overtake native plants, affect water availability or damage the quality of soil among other potential impacts.

Here are some resources to help you identify various invasive plants in woodland areas near you, to know when to report them and also what you can do help control their spread.

Invasive Asian bush honeysuckle species in spring

The longer daylight period and the warming weather are bringing new life to woodlands. We have a community of native plants, called spring ephemerals, that grow, bloom, and produce seed quickly before the tree leaves emerge and the forest understory is wrapped in shade. Several of my favorite wildflowers are in this group, including hepaticas, trilliums, bloodroot, squirrel-corn, and trout lily.

Some unwelcome invaders also emerge early in the spring, producing early foliage and an unnatural shade competing with our native plants. Several woody invasive plants have moved into our woodlands from ornamental and other plantings and now compete aggressively with our natives. These include Asian bush honeysuckles, privets, winged burning bush, and multiflora rose. These plants tend to produce foliage faster than most of our native trees and shrubs, proving them with a competitive advantage through a longer growing season. This early leaf emergence also provides us with an opportunity to identify these invaders in our woodlands. When walking out to observe the wildflowers or hunt for morels, keep your eyes open for the invasive plants. Small specimens can be pulled when soils are moist. Larger specimens may be cut and the stump treated with a herbicide to prevent sprouting. An easy and effective herbicide to access for landowners is glyphosate concentrate products mixed at a 50% ratio with water. Apply this mixture to the cut stump immediately after cutting. Read the herbicide label to understand the protective gear and application instructions required to apply safely.

If you have a large infestation that is beyond your capacity to control, consider contacting a local forester or other natural resources professional for advice on how best to deal with your invasive plant problem. You may contact the Indiana DNR Division of Forestry for advice from the District Forester.  Private-sector foresters and environmental groups and contractors may also be able to help you manage invasive species on your property. To find a private-sector forester visit www.findindianaforester.org. You can find environmental groups and contractors, and additional information on invasives at the Indiana Invasive Species Council website. Purdue Extension has many invasive species resource publications and videos that can help with identification and management.

Controlling invasive plants can bring a sense of satisfaction, knowing you are doing something to promote the health and sustainability of your property.

Winged Burning BushWinged burning bush, winged euonymus, or simply burning bush (Euonymus alatus) is a medium-sized deciduous shrub native to China, Japan and Korea but is widely planted in the United States. Winged burning bush has been planted in the US since the 1860s, primarily as an ornamental shrub due to its bright red fall foliage. Reports of this species escaping cultivation and establishing in natural areas, such as woodlands, prairies and other uncultivated areas, emerged in the 1970s in the Northeast and Midwest US. The species is now considered invasive in most of the eastern US, including Indiana.

Invasive Plant Series: Winged Burning Bush is an 8-page publication written by experts Brian Beheler, farm manager, Don Carlson, forester, Lenny Farlee, sustaining hardwood extension specialist and Ron Rathfon, regional extension forester SIPAC. In this publication, you can learn about the identification, distribution, impact, management and control of this deciduous shrub found in Indiana hardwood forests. For more information check out the Burning Bush Video.

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.
