How many ferns (that is a plural!) between the trees?If there are equal numbers of ferns in between each pair of trees: Five times as many ferns as between one pair.
The feature between conifers and ferns are that they both are vascular plants the grown in a humid temperate environment. They differ in that a conifer is a seed producing plant and the fern more primitive reproduces with spores.
There is very little difference between prehistoric ferns and ferns of today. However, there are hundreds to thousands of fern species that are no longer around today. This is due to changes in topography, climate and time. Many of today's species are evolved or remain unchanged. But they are prone to the same
Ferns are green plants.So they do have chloroplasts.

They have stems, leaves, and roots like other vascular plants. Ferns reproduce via spores and have neither seeds nor flowers.By far the largest group of ferns is the leptosporangiate ferns, but ferns as defined here (also called monilophytes) include horsetails, whisk ferns,marattioid ferns, and ophioglossoid ferns. The term pteridophyte also refers to ferns and a few other seedless vascular plants (see classification section below).Ferns first appear in the fossil record 360 million years ago in the Carboniferous but many of the current families and species did not appear until roughly 145 million years ago in the early Cretaceous (after flowering plants came to dominate many environments).Ferns are not of major economic importance, but some are grown or gathered for food, as ornamental plants, for remediating contaminated soils, and have been the subject of research for their ability to remove some chemical pollutants from the air. Some are significant weeds. They also play a role in mythology, medicine, and art.
