I present some results from studies identifying environmental drivers of vital rates and population dynamics when controlling for intraspecific density statistically or experimentally, show that density dependence can be strong even in populations of slow-growing species in stressful habitats, and argue that controlling for density will often be necessary for identifying spatial variation in environmental drivers of demographic patterns in plants.
