Here I've a book that specialises in forestry management and talks of young, early successional habitat and mature forest....HTH

"There are many questions about “why, what, where, and how” to manage for ***early successional habitats***. Tradeoffs among ecological services such as carbon storage, hydrologic processes, forest products, and biotic diversity between ******young, early successional habitats and mature forest are not fully understood********. Personal values and attitudes regarding forest management for conservation purposes versus "letting nature take its course," complicate finding common ground on whether and how to create or sustain early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address critical questions sparked by the decline of early successional habitats.
