"...LINNE will support and benefit from linkages to a wide range of activities in ecology, ecosystem science, bioinformatics, information sciences, geology, land planning, and resource management, ... "

balance seems a good translation for Haushalt in this context

Linne is better known in EN as Linnaeus:

You may find that the term 'taxonomy' is helpful here as a possible translation:

"... the academic discipline of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. Each group is given a rank and groups of a given rank can be aggregated to form a super group of higher rank and thus create a hierarchical classification."

Linnaeus's system is no longer used. It has been replaced by biological systematics and/or taxonomy, as previously stated:

Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components, branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth.

"Systematic biology" and "taxonomy" (terms that are often confused and used interchangeably) were defined in relationship to one another as follows:[1]


Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f) considers their environmental adaptations. This is a field with a long history that in recent years has experienced a notable renaissance, principally with respect to theoretical content. Part of the theoretical material has to do with evolutionary areas (topics e and f above), the rest relates especially to the problem of classification. Taxonomy is that part of Systematics concerned with topics (a) to (d) above.

The term "systematics" is sometimes used synonymously with "taxonomy", and may be confused with "scientific classification". Europeans tend to use the terms "systematics" and "biosystematics" for the field of the study of biodiversity as a whole, whereas North Americans tend to use "taxonomy" more frequently. [2] However, taxonomy, and in particular alpha taxonomy, is more specifically the identification, description, and naming (i.e. nomenclature) of organisms,[3] while "classification" is focused on placing organisms within hierarchical groups that show their relationships to other organisms. All of these biological disciplines can be involved with extinct and extant organisms. However, systematics alone deals specifically with relationships through time, and can be synonymous with phylogenetics, broadly dealing with the inferred hierarchy of organisms.

Naturhaushalt = ecological balance appears to be more proper in this context.

Because the text mentions that

Naturhaushalt wird einmütig als Wirkungsgefüge der Landschaftsfaktoren Relief, Gestein, Boden, Klima, Wasser, Luft, Pflanzen und Tiere definiert.

That means, the text talks of an ecological balance between these various factors mentioned herein.
