ABOUT: Integrated Weed Management
Ondine Freshwater Consultants LLC uses a set of industry and scientific best practices to help develop preventative measures as well as responses to issues. Together, these five areas form an integrated management planning approach:
​
​
Preventative Preventing problems is the goal of all professionals who care for freshwater bodies. Prevention
Measures can be as simple as identifying a possible issue, like the presence of invasive species nearby or the
presence of a dirt road that could contribute to excessive sedimentation in a pond in the future.
Preventative measures may have a cost associate with it, however, such as imploring the use of
aeration to prevent excessive algae growth, or planting native bushes and shrubs to prevent bank
erosion.
​
Biological Biological management is the use of biological entities such as plants, insects, or other species in order to manage a particular concern. An example of this is allowing goats or sheep to
graze in a particular area to reduce the growth of a target plant growing in a field or installing
native species along the edge of a waterbody to filter out nutrients from ground water from
entering the water column.
Chemical Just hearing the term 'Chemical management' can make people upset when discussing
environmental care and restoration. However, chemical management options are often
misunderstood, especially as many chemicals available to control invasive species are engineered
from organic, naturally occurring chemicals, and are designed to break down back into their
naturally occurring chemical building blocks within the microbial environments of soil and
water. Without herbicides, many ecosystems infested with invasive species would collapse
entirely.
Additionally, there are several products produced with naturally occurring chemicals
harvested from other species like kept or that utilize important enzymes and microbial life that
are helping restore the natural conditions of ponds that have been altered by unnatural processes
or conditions.
​
At Ondine Freshwater Consultants LLC, we do not utilize herbicides in our integrated
management. However, we do consult and work with well managed, licensed herbicide
application companies whose services can be vital to the survival of ecosystems, especially when
considering large infestations of invasive species.
Cultural Cultural management is management which addresses the behavior changes that are needed in
order to address a particular management challenge. For example, cultural management
planning might require moving a dock that could be causing erosion on a particular area of a
pond. Another example is planting specific species to bring shade, ground coverage, or nutrient
control in order to prevent an invasive plant from taking over.
​
Mechanical Mechanical management techniques includes terrestrial activities ranging from hand removal to
tilling, moving, cutting, plowing, and raking. It also includes aquatic activities such as aeration,
filtration, aquatic weed removal through diver assisted suction harvesting, diver assisted dredging,
and aquatic weed cutting and raking.

Owner Hannah K. Sotak is an 8-year veteran of the US Coast Guard, working scuba diver/tender, and a post-graduate student at the University of Florida currently working on a Weed Science Management Certification. Hannah's favorite place to be is in the water, submerged on SCUBA if possible. Having last worked as both a site supervisor and science manager for a large commercial diving company performing invasive weed control, Hannah's combination of experience and education drive her passion for freshwater consulting & management. She believes most pond and lake problems are best answered with holist, integrated strategies that work with the natural conditions and characteristics of that ecosystem.
​
Prior to working in the field of limnology and freshwater management, Hannah received a Master's of Divinity from Boston University and served as professional clergy for several years. Her current ministry appointment is to continued education in aquatic sciences and water management. She seeks to unite her spiritual beliefs of the responsibility of all people to care for the earth and its resources while employing cutting edge scientific research and best practices. Hannah's focus is primarily on limnological environments, or freshwater bodies, and water management practices.
​
Hannah lives with her husband and children in Manchester, Vermont, and is an avid diver, nature photographer, and writer. Her non-profit, Re-Wilding the Spirit, provides free resources on theocology, public speaking engagements, and resources for children and their families who wish to explore the connection of faith and science.
