This process, known as biological nitrogen fixation (BNF), bypasses the need … Read more

Trees face one of their most punishing challenges when exposed to salt — whether from ocean spray, coastal winds, or road deicing chemicals. Salt draws moisture out of plant tissues, disrupts nutrient uptake, and can poison the soil over time. Despite this, a remarkable group of trees has evolved or adapted to not only survive … Read more
