Conservation-Friendly Farming Can Benefit Both Birds and Crops

Completely, our work suggests that wide-scale conservation of natural habitat will assist promote birds to maximize their benefits to conservationists and farmers, while minimizing their harms to farmers and human health. However, we also have a long way to go to incentivize farmers and other personal landowners to do so.
Olivia Smith is a research study partner in the Ecology, Evolution, and Behavior Program at Michigan State University.

I like birds and bird watching– from the aerial twists and turns of the nimble barn swallow, to the sally and hover of a flycatcher capturing a moth, to the cute leading knot of the rotund California quail. Birds bring me fantastic personal satisfaction and specify a part of my being.
The technical scientific term for this is a “cultural environment service”– the non-material advantages that ecosystems and biodiversity therein offer to individuals.
One crucial location for bird preservation is in farmlands. Yet, preservation of birds in agricultural systems is a complex issue, in part due to it being private land, and in part because birds play lots of functions that affect crop production.

On the other hand, promoting predatory bird species like the American kestrel may deter fruit-eating birds, improving yields and the financial well-being of farmers.

Such controversies have typically resulted in dispute over conservation-friendly farming– is farming in consistency with preservation efforts increasing the benefits or dangers from birds?
This inspired me to state to study birds and farming practices over 4 summers on 27 varied farms throughout the US West Coast states of Oregon and Washington.
Through this, I was able to maximize my life list by observing 15,682 people from 111 types throughout the designated bird study periods alone. I saw species such as stunning lazuli buntings, adorable bushtits, and iconic ospreys. I saw intriguing interactions such as a blackbird mobbing a crow, who turned and began mobbing an osprey, who then turned and started mobbing a bald eagle.
I then analyzed my more than 15,000 bird observations with input from collaborators at The Nature Conservancy and numerous universities to examine how conservation-friendly farming practices and plentiful natural habitat in the broader landscape (a 2.1-km circle around where I surveyed) impact the impacts of birds on farms and conservation efficacy.
That is, how can we manage farms to promote the benefits of birds and decrease damage?
Overall, we found that a private farmer can implement conservation-friendly farming practices to promote advantageous birds– consisting of both birds that consume insects and birds that supply cultural services to the farmers.
The farmer could, for instance, offer hedges to promote insect-eating birds near crops that are being harmed by insects. They might also take actions such as integrating animals into their farm, which can benefit birds through additional meadow (e.g., northern harrier and savannah sparrow nest sites) and structures to nest on (e.g., barn swallow and cliff swallow nest sites). Another strategy could be retaining riparian areas or wetlands that can promote birds and provide other crucial sustainability advantages such as disintegration control.
The problems associated with birds, nevertheless, were more impacted by the quantity of natural environment in the wider landscape than what the specific farms were doing. This implies that to minimize harms related to birds, there requires to be neighborhood management of farming systems.
Organizations such as TNC or Audubon Society have programs in location to do so such as Audubon Certified Grazed on Bird Friendly Land. Nevertheless, there will likely need to be greater community-wide uptake by farmers to actually optimize the advantages of birds to farming while reducing problems from birds.
