Approximately 70% of Nightcap NP is covered by a variety of rainforest communities, and the rest is covered by mostly wet sclerophyll forest and partly dry sclerophyll forest. The park also supports lowland species of the former Big Scrub, which was the largest area of subtropical lowland rainforest that was intensively cleared; now less than 1% remains.<ref name=":2" /> Of all the known native vascular flora in NSW about 10% of it can be found here with 72 that are identified as threatened with extinction. The park supports a rich diversity of species that includes more than 40 species of mammals, 27 reptiles, 23 frogs, over 140 bird species, over 650 known plant species including numerous ferns and various orchids, and a diverse variety of fungus and lichens.<ref name=":4">{{Cite web|title = Environment & Heritage {{!}} NSW BioNet|url = http://www.environment.nsw.gov.au/atlaspublicapp/UI_Modules/ATLAS_/AtlasSearch.aspx|website = www.environment.nsw.gov.au|access-date = 2015-05-19}}</ref><ref>{{Cite web|title = Bushwalks|url = http://rosebank.ws/bushwalks.html|website = rosebank.ws|access-date = 2015-05-21}}</ref>

As of 2011, Forests of East Australia became the 35th Biodiversity Hotspot, which includes Nightcap NP. The concept of the Biodiversity Hotspot is that there are "exceptional concentrations of endemic species that are undergoing exceptional loss of habitat".<ref>{{Cite web|title = CSIRO Research Publications Repository - Forests of East Australia: The 35th Biodiversity Hotspot|url = https://publications.csiro.au/rpr/pub?list=BRO&pid=csiro:EP101404&sb=RECENT&n=14&rpp=25&page=56&tr=5047&dr=all&dc4.browseYear=2011|website = publications.csiro.au|access-date = 2015-05-19}}</ref><ref>{{Cite web|title = Forests of eastern Australia are the world's newest biodiversity hotspot|url = http://theconversation.com/forests-of-eastern-australia-are-the-worlds-newest-biodiversity-hotspot-3935|access-date = 2015-05-19|first = Karl|last = Vernes}}</ref>
