Najas minor grows earlier in the season than many native plants, and gain an advantage for survival by accessing necessary light and nutrients with no competition for resources. Because of their quick growth early on, these plants crowd out native plants and prevent them from receiving sunlight and space for growth. Dense communities of these plants can produce unfavorable environments for fish and waterfowl, potentially displacing them, as well as the plants they directly displace. They've also been noted to increase sedimentation rates and clog waterways in several states. In regards to humans, brittle naiad can reduce recreational value of waterways as well as the aesthetic value of nearby scenic locations. This plant spreads through its seeds or fragmentation. Waterfowl transport the seeds and further the species' spread. These plants have highly branched stems that fragment easily, allowing transportation with water movement. Humans often aid in their transportation by spreading fragments and seeds that get onto boats and boat trailers.
