I ’ve understand kudzu ’s sprawling vine blanket Sir Herbert Beerbohm Tree , household , and entire fields , leaving a lead of suffocated vegetation in its viewing . Its behavior is both absorbing and frustrating , as it thrives on rapid increment and an almost unrelenting spread .

While kudzu might ply some fleeting shade and temporary shelter for small creatures , its overall impact on local ecosystems is overwhelmingly damaging .
