Invasive Honeysuckle Bushes Outcompete Native Species for Sunlight Tipping Kansas Ecosystem

Due to the invasive honeysuckle bushes' rapid growth rate, which outcompetes native plant species for sunlight, Kansas' ecosystem is out of balance.

Invasive Honeysuckle Bushes in Kansas

The invasive honeysuckle plant, with its sweet fragrance and visually appealing presence, is quietly seizing control of outdoor spaces throughout Kansas. Local authorities convened to address the escalating issue, particularly focusing on the more aggressive bush variety. This aggressive growth is causing concern for the Kansas Forest Service (KFS), prompting Forest Health Coordinator Ryan Rostok to emphasize ongoing efforts to curtail honeysuckle's encroachment.

During the current season, bush honeysuckle stands out in local green areas and forests with its distinctive white flowers in spring and red berries in the fall. Rostok highlighted the unique challenge posed by honeysuckle, which retains its greenery longer into the season than native trees, complicating containment measures as trees enter dormancy.

Ecosystem Imbalance: Diversity, Sunlight, and Pollinators

Invasive species wield a transformative impact on ecosystem food webs, either by annihilating or supplanting indigenous food sources, often offering little sustenance for local wildlife. They can also disrupt the abundance and diversity of species crucial for native wildlife habitats. Aggressive plants like kudzu swiftly replace diverse ecosystems with monotonous monocultures.

Furthermore, certain invasive species can modify ecosystem conditions, such as altering soil chemistry or amplifying wildfire intensity.

Forest Health Coordinator Ryan Rostok underscores the formidable threat posed by honeysuckle, particularly in Kansas's eastern third, due to its persistence and hardiness. Once entrenched, removing honeysuckle proves challenging, as it seizes the understory, ousting native plants and monopolizing sunlight.

This monopoly leads to a decline in plant diversity, replaced by the invasive honeysuckle. Rostok notes its early leafing and late leaf-shedding, making it the understory's dominant monocrop, outcompeting diverse native vegetation essential for ecosystem health and pollinators.

Honeysuckle Eradication

Efforts to combat invasive honeysuckle in Shawnee County, led by Park District Manager Tom Hammer of Shawnee County Parks and Recreation (SCP+R), have persisted since he arrived in 1999. The impact is palpable in areas like Skyline Park, Dornwood Park, and along the Shunga Trail, prompting SCP+R to allocate approximately $5,000 annually for control measures.

Hammer employs a multifaceted approach to honeysuckle control, utilizing herbicides, mowing, and controlled burns, adapting strategies to specific areas. Ryan Rostok, Forest Health Coordinator at the Kansas Forest Service (KFS), collaborates on awareness and anti-invasive strategies. While private landowners have removal options, established honeysuckle proves challenging to control.

Rostok emphasizes public awareness, particularly in mid to late November when deciduous forests unveil the scale of the issue. Honeysuckle's persistent greenery, an advantage over native species, aids identification for targeted herbicide application in the fall. Hammer advises frequent yard mowing to thwart bush honeysuckle establishment, given its rapid growth and potential property overruns if unchecked.

Conservationists leverage honeysuckle's extended greenery, singling it out for effective herbicide application in the fall. Despite its competitive advantage, honeysuckle's traits are being turned against it in the ongoing efforts to curb its invasive spread. The struggle against honeysuckle continues as SCP+R remains steadfast in its commitment to preserving local ecosystems.
