Number of Livestock Breeds and Plant Varieties (Z1)
 

Livestock breeds and plant varieties become threatened with extinction once they are no longer of economic use. This is particularly true for heirloom breeds and varieties, unless specific efforts are made to ensure their preservation. At the same time, new breeds and varieties emerge, and import barriers for livestock breeds have been removed. The Z1 indicator provides an overview of these developments.

Genetic diversity is essential for conserving biodiversity, which may be diminished even without an entire species going extinct. The risk for this to happen has increased in recent decades, as agriculture has been focusing on breeding or cultivating only a few breeds and varieties for the sake of maximum yield. For this reason, special efforts are required to preserve heirloom breeds/varieties and their specific genetic properties.

The Z1 indicator provides a synopsis of both herdbook-registered livestock breeds kept in Switzerland and crop plant varieties of select species earmarked for preservation.

Interpretation example
In 2001, there were five herdbook-registered pig breeds in Switzerland. In 2002, they were complemented by the Large White Sire Line breed.

Comment
• As a result of the new Swiss Ordinance on Livestock Breeding taking effect in 1999 and import restrictions being lifted in 1995, the number of livestock breeds has been increasing since 1999. The Federal government subsidizes breeders’ services supplied by recognized breeders’ associations regardless of breed. Breeding objectives are determined by individual breeders’ organizations.
• It is mainly beef breeds that caused the number of cattle breeds to increase from 19 to 29.

Interpretation example
In 2009, the potato positive list in the Swiss National Database contained 97 varieties deemed worthy of preservation.

Comment
• The table above is a summary based on positive lists established as part of the FOAG’s National Action Plan for the Preservation and Sustainable Use of Plant Genetic Resources for Nutrition and Agriculture PGRNA and downloaded from the website of the Swiss National Database BDN (www.bdn.ch, data status: June 2009). These BDN positive lists include all varieties meant to be preserved by the PGRNA program, provided their identity has been verified and at least one accession—i.e. concrete specimen—of each is available in primary plant collections. Data are restricted to varieties of species which are also covered by the Z2 indicator. At this time, the Swiss National Database is still under construction.
• While the number of varieties is immense, only a few varieties are cultivated on large crop areas (cf. Z2 indicator).

Significance for biodiversity
 

Conserving livestock breeds and crop plant varieties saves the genetic diversity of the organisms we depend on for food production. This genetic diversity harbors an important potential for responding to parasite infestations, infectious diseases, or epidemics.

As opposed to the past, when the Federal government only subsidized 18 official Swiss livestock breeds, it now supports all breeds since the new Ordinance on Livestock Breeding took effect in 1999. Furthermore, the new Ordinance also allows breeders’ associations to determine breeding objectives themselves, which makes for much more diverse breeding activities. Since the Convention on Biological Diversity was ratified, rare and endangered livestock breeds are being monitored and subsidized by specific programs. For all of these reasons, it is at present unlikely for any of the livestock breeds listed by the Z1 indicator to go extinct in Switzerland.

Looking at crop plants, the situation is completely different insofar as the number of varieties surpasses the number of breeds by far, making it all the more challenging to identify, describe, and conserve them. Very aware of the importance of this task, the Federal Office for Agriculture has established the National Action Plan for the Preservation and Sustainable Use of Plant Genetic Resources for Nutrition and Agriculture (PGRNA) for precisely that purpose.
