Which easement type can vary by individual need rather than benefiting specific parcels of land?

An easement in gross is characterized by being personal in nature and not tied to a specific piece of land. Instead of benefiting a parcel of land, it benefits an individual or entity, allowing them to use the property in a designated way. This type of easement can vary according to individual needs, as it is created for the advantage of the holder rather than to serve the land itself.

In contrast, an appurtenant easement is attached to a specific parcel of land and its benefits are inherent to that property, making it dependent on both the dominant and servient estates. A conservation easement serves to protect a specific area for conservation purposes, typically benefiting the public interest rather than individual needs. An implied easement arises from the actions or circumstances indicating that one party has the right to use another's property, and it too is linked to the specific land rather than an individual's preferences. Thus, the most fitting answer to the question is that an easement in gross caters to personal requirements, distinguishing it from other easements that are linked to specific parcels or purposes.
