Common ragweed invasion poses serious risks to human health, biodiversity and agricultural production throughout the world. Although ragweed has an enormous potential to expand its range in Turkey, studies on ragweed have only concentrated on the Black Sea region. An exploratory survey was conducted to observe the level of ragweed occurrence on the nodes of predecided 10 × 10 km grids in the Thrace region of Turkey. Ragweed populations were observed in 44 out of 129 sites in a wide range of habitats, including roadsides, pastures, agricultural fields and non-agricultural areas. The highest levels of ragweed infestation were recorded in the agricultural fields, followed by the roadsides. The most-invaded crop was sunflower. The sunflower fields had the highest ragweed coverage as well and invasion even resulted in crop failure alongside the field borders. A spatial analysis of the data indicated that ragweed exhibited an aggregated pattern over the Thrace region. Ragweed distribution was not associated with the characteristics of the soils, which had a varying range of pH, electrical conductivity and texture. The results revealed that ragweed invasion can arise as a serious weed problem, interfering with the sustainability of sunflower production in Thrace and other sunflower-producing regions of the country. A high degree of ragweed infestation also will contribute to the pollen level counts for the most crowded cities in the region, posing a serious danger to human health.

“…Data on relative abundance of invasive species and their locations can permit creation of detailed maps showing their current extent (USFWS 2016), and data can be entered into modeling programs to predict the future spread on the landscape (Rawlins et al 2011). Following an assessment of the abundance and distribution of invasive species, decisions on the best areas for restoration and or control/eradication can be made (FICM-NEW 2003;Rew and Pokorny 2006;Rawlins et al 2011;Welch et al 2012;USFWS 2016).…”

“…An early approach to rapid assessment of invasive plants can be found in the Federal Interagency Committee for the Management of Noxious and Exotic Weeds (FICM-NEW) (FICM-NEW 2003). The U.S Fish and Wildlife Service (USFWS), including the National Wildlife Refuge System (NWRS), follow national data standards established by the North American Invasive Species Management Association (NAISMA) (Welch et al 2012;NAISMA 2014;USFWS 2016). These data standards can be used in a rapid assessment approach to document the specific invasive species present, provide an estimate on abundance, and to map the distribution of invasive species on USACE project lands.…”

“…This approach requires little to no field work, except to verify presence and location of invasive trees on the project land. This approach may be preferable if the area to be surveyed is very large (e.g., > 1,000 ha) (Welch et al 2012). Application of this approach requires procurement of high resolution (1 m to 4 m) aerial or satellite imagery and may require an experienced GIS technician.…”

“…Often, this approach represents the first effort to determine presence of invasive tree species, and generally reflects the Early Detection and Distribution Mapping System (Rawlins et al 2011). Similar approaches are used by the National Invasive Species Council (NISC 2003), USFWS (USFWS 2016), the U.S. Geological Survey (USGS) (Welch et al 2012), and the U.S. Department of Agriculture (USDA) (Rew and Pokorny 2006). To survey an area for invasive species, the observer stands at a predetermined location and records all invasive trees detected and their general location within the area of view (Figure 1).…”

(ERDC-EL), to provide an introduction to rapid assessment methods that can be used to provide a quantitative index to the abundance and distribution of invasive riparian trees found on U.S. Army Corps of Engineers (USACE) project lands. The USACE Ecosystem Management and Restoration Research Program (EMRRP) is supporting a nationwide effort to address the impacts of invasive tree species that affect decision making and the ultimate success of ecosystem restoration efforts. This research project has four objectives: (1) identify the suite of invasive woody riparian trees that are most problematic to USACE ecosystem restoration efforts, (2) develop guidelines that suggest thresholds for when and where on the landscape funds should be spent to control invasive trees, (3) determine the most efficient and ecologically-effective spatial configuration for woody invasive riparian plant removal on Corps-managed lands, and (4) investigate how faunal communities respond to various spatial control methods for invasive tree removal in densely vegetated riparian habitats. Guilfoyle and Fischer (2016) provide an introduction to invasive riparian trees found on USACE project lands that may impact USACE restoration efforts. This TN follows that effort by: (1) detailing approaches USACE personnel can employ to rapidly assess the abundance and distribution of invasive riparian trees and other plants on project lands, (2) to use these data to make decisions about degree of control needed to protect or restore important native riparian communities, (3) to introduce other methods to intensively survey and manage invasive populations and assess restoration success, (4) identify the best locations where cost-effective approaches to riparian habitat restoration is most likely to be successful, and (5) to provide guidance on the best removal or control spatial configurations that will yield the best restoration outcomes.

Managers tasked with controlling invasive species require effective methods that are quick and easy to use without inflicting extensive nontarget damage, while also being compatible with other scheduled management responsibilities. Lonicera maackii (Amur honeysuckle) is a non‐native shrub that has invaded eastern and midwestern North American deciduous forests, altering ecosystem function and reducing biodiversity. This study explores prescribed fire and seasonal basal applications of triclopyr ester as control methods and examines the extent of nontarget damage. We used paired‐split plots to implement basal bark treatments in different seasons within burned and unburned units, and we tracked individual L. maackii to determine mortality and hyperlocal impacts of management. Basal bark treatments killed 98.4% of L. maackii across seasonal timings. Nontarget plant cover declined similarly for all herbicide application seasons, but there were some signs of recovery within 4 years, and the early‐ and late spring treatments were less affected overall. Species richness showed biologically small but statistically different declines across treatment times. Prescribed fire did not impact L. maackii mortality or interact with herbicide efficacy. Basal bark applications of triclopyr are an effective means of L. maackii control regardless of application timing, which allows managers to implement it at their convenience to avoid interfering with other management tasks that have time constraints.
